A1 adverb #1,500 最常用 11分钟阅读

todavía

前1,500

At the A1 level, 'todavía' is introduced as a simple time marker meaning 'still' or 'yet'. Students learn to use it in basic affirmative sentences like 'Todavía estoy en casa' (I am still at home) and in the very common negative phrase 'todavía no' (not yet). At this stage, the focus is on recognizing the word in daily conversation and using it to describe ongoing states. It is one of the first adverbs of time learners encounter because it is essential for answering questions about whether an action has been completed. A1 learners should focus on the fixed phrase 'todavía no' as a complete answer to questions like '¿Has terminado?' (Have you finished?). This level also introduces the contrast with 'ya' (already), helping students distinguish between something that is continuing and something that has just happened.

At the A2 level, learners expand their use of 'todavía' to include more complex verb tenses, particularly the present perfect. You will learn to say things like 'Todavía no he visto esa película' (I haven't seen that movie yet). The focus shifts to the placement of 'todavía' within a sentence and its role in managing expectations. A2 students begin to understand that 'todavía' often implies that something is expected to change. For example, 'Todavía es temprano' (It's still early) suggests that it will eventually be late. You will also start to see 'todavía' used in questions to express mild surprise: '¿Todavía estás aquí?' (Are you still here?). This level reinforces the 'todavía no' vs 'ya no' distinction, which is a common point of confusion for elementary learners.

At the B1 level, you will start using 'todavía' to emphasize comparisons. This is a significant step up from its use as a simple time marker. You will learn to use 'todavía más' (even more) or 'todavía mejor' (even better) to add intensity to your descriptions. For example, 'Este examen fue todavía más difícil que el anterior' (This exam was even harder than the previous one). B1 learners also encounter 'todavía' in more varied contexts, such as in the past tense ('Todavía vivía allí cuando lo conocí' - I was still living there when I met him). You will also begin to recognize the synonym 'aún' and understand that while it means the same thing, 'todavía' remains the preferred choice for spoken communication and informal writing.

At the B2 level, 'todavía' is used in more nuanced ways, often in conjunction with the subjunctive mood or in concessive clauses. For example, 'Aunque todavía no haya llegado, debemos empezar' (Even though he hasn't arrived yet, we must start). B2 students explore the use of 'todavía' in expressing persistence in the face of obstacles. You will also learn idiomatic expressions like 'todavía y con eso' (even so). At this level, the distinction between 'todavía' and 'aún' becomes more important for writing style; you might choose 'aún' to avoid repetition in a long paragraph. You will also use 'todavía' to express a sense of 'even' in more abstract scenarios, such as 'Todavía si fuera verdad...' (Even if it were true...).

At the C1 level, 'todavía' is mastered in all its stylistic and grammatical variations. You will use it to create sophisticated temporal structures and to add rhetorical weight to your arguments. C1 learners understand the subtle rhythmic differences between 'todavía' and 'aún' and can use them to vary the tone of their prose. You will encounter 'todavía' in complex literary texts where it might be used to evoke a sense of timelessness or historical continuity. You will also be comfortable using it in professional and academic settings to describe ongoing research or unresolved legal issues. The focus at this level is on perfect integration into natural, high-level discourse, ensuring that its placement and emphasis align perfectly with the intended message.

At the C2 level, 'todavía' is used with the precision of a native speaker. You will understand its historical evolution from 'totā viā' and how this informs its use in archaic or highly formal texts. C2 learners can use 'todavía' to express very subtle shades of meaning, such as irony or extreme skepticism. You will be able to handle 'todavía' in any dialectal variation of Spanish, recognizing how its frequency might change across different regions of the Spanish-speaking world. At this level, the word is no longer a 'vocabulary item' but a versatile tool for precision in thought and expression. You can use it in high-level debating, literary analysis, and complex creative writing to manage time and degree with absolute fluency.

todavía 30秒了解

Todavía is a high-frequency Spanish adverb primarily meaning 'still' or 'yet', used to indicate the continuity of a state or action from the past into the present.
In negative sentences, it forms the phrase 'todavía no' (not yet), which is essential for expressing that an expected action has not occurred but is anticipated.
It can also be used with comparative adjectives (e.g., todavía más) to mean 'even', adding emphasis to the degree of difference between two things being compared.
It is a versatile word used across all levels of Spanish, from basic A1 greetings to complex C2 literary analysis, making it a core vocabulary requirement.

The Spanish adverb todavía is a fundamental pillar of temporal expression in the Spanish language. At its core, it functions to indicate that a state or action continues to exist or occur up to the present moment, or up to a specific point in time being discussed. In English, it is most frequently translated as 'still' or 'yet', depending on the grammatical context and whether the sentence is affirmative or negative. Understanding 'todavía' requires grasping the concept of continuity—it bridges the past with the present, suggesting that something started previously and has not ceased.

Temporal Continuity: It marks the persistence of a situation. If you say 'Todavía llueve', you are stating that the rain began in the past and is continuing right now.

¿Todavía estás en la oficina? Es muy tarde.

Beyond simple time, 'todavía' carries a weight of expectation. When used in the negative form, 'todavía no', it implies that while an action hasn't happened yet, there is an anticipation that it will happen in the future. This distinguishes it from 'no', which is a simple negation. 'No he comido' (I haven't eaten) is a fact; 'Todavía no he comido' (I haven't eaten yet) suggests I plan to eat soon. This nuance is vital for fluid conversation and expressing intent.

Comparative Emphasis: In higher-level Spanish, 'todavía' is used to intensify comparisons, similar to 'even' in English. For example, 'Este libro es todavía mejor' (This book is even better).

La situación es todavía más complicada de lo que pensábamos.

Etymologically, 'todavía' comes from the Latin phrase 'totā viā', which literally translates to 'by every way' or 'all the way'. This historical root helps explain its modern meaning of 'continuing along the path' of time. Whether you are a beginner learning to say 'I'm still here' or an advanced student discussing complex temporal relations, mastering this word is essential for natural-sounding Spanish. It appears in roughly 0.05% of all spoken Spanish, making it one of the top 500 most frequent words.

Expectation vs. Reality: It often highlights a discrepancy between what was expected to change and what remains the same.

Aunque pasaron diez años, todavía guardo sus cartas.

¿No has terminado todavía? El tren sale en cinco minutos.

Ella todavía no sabe la noticia, por favor no digas nada.

Using 'todavía' correctly involves understanding its placement and its interaction with verb tenses. In affirmative sentences, 'todavía' usually precedes the verb, though it can also be placed at the end for emphasis. For example, 'Todavía vive aquí' (He still lives here) is the standard structure. If you place it at the end, 'Vive aquí todavía', it often carries a tone of surprise or questioning. In negative sentences, 'todavía no' is the most common construction, where 'todavía' almost always precedes 'no'.

The 'Todavía No' Rule: When expressing 'not yet', 'todavía' must come before 'no'. Example: 'Todavía no he terminado' (I haven't finished yet).

El paquete todavía no ha llegado a la casa.

One of the most important distinctions for learners is the difference between 'todavía' and 'ya'. While 'todavía' implies continuity (still), 'ya' implies a change of state (already/now). 'Todavía fumo' means I still smoke; 'Ya no fumo' means I no longer smoke. This 'state change' logic is crucial for mastering Spanish time markers. 'Todavía' is also used with comparatives to mean 'even'. In this case, it precedes the comparative adjective: 'todavía más grande' (even bigger), 'todavía menos' (even less).

Placement for Emphasis: While usually before the verb, placing it at the very end of a sentence can emphasize the duration. '¿Estás aquí todavía?'

Es todavía más difícil de lo que parece a primera vista.

In terms of register, 'todavía' is universal. It is used in formal writing, academic papers, casual conversation, and poetry. However, in very formal or literary contexts, you might see 'aún' used more frequently to avoid repetition or to achieve a specific rhythmic effect. For the learner, 'todavía' is the safer, more natural choice for 95% of situations. It is also used in the phrase 'todavía y con eso' or 'con todo y con eso' to mean 'even so' or 'nevertheless', although this is more advanced.

Interaction with Gerunds: It is very common with the present continuous: 'Todavía estoy trabajando' (I am still working).

¿Todavía sigues pensando en lo que pasó ayer?

Aunque es invierno, todavía hace un poco de calor por las tardes.

No podemos irnos, todavía falta que llegue Juan.

You will encounter 'todavía' in almost every corner of Spanish-speaking life. In the domestic sphere, it’s the word of choice for parents asking children if they’ve finished their homework ('¿Todavía no has hecho los deberes?') or for family members checking if dinner is ready. In the workplace, it’s used to discuss project statuses, deadlines, and ongoing tasks. If you are waiting for a bus or a train, you might hear someone say 'Todavía no viene' (It’s not coming yet).

In Popular Music: Spanish lyrics are full of 'todavía' because it perfectly captures the longing of 'still loving someone'. Think of songs like 'Todavía' by La Factoría.

'Porque todavía te amo y no puedo olvidarte', dice la canción.

In the news and media, 'todavía' is used to report on developing situations. Journalists use it to describe conflicts that haven't been resolved, laws that are still being debated, or weather conditions that persist. For example, 'Todavía se desconocen las causas del incendio' (The causes of the fire are still unknown). It provides a sense of 'breaking news' or ongoing relevance that is essential for journalistic reporting.

In Customer Service: You'll hear it when checking on orders: 'Su pedido todavía está en proceso' (Your order is still being processed).

¿Todavía no le han atendido, señor?

In literature and cinema, 'todavía' is a powerful tool for building tension or emotional depth. A character might realize they 'still' have hope, or a narrator might describe a town that 'still' looks the same after fifty years. It’s a word that connects the past of the story to the present moment of the reader. In films, it’s often used in dramatic confrontations: '¿Todavía te atreves a venir aquí?' (Do you still dare to come here?).

In Daily Errands: At the bakery: '¿Todavía tienen pan integral?' (Do you still have whole wheat bread?).

El médico todavía tiene pacientes esperando en la sala.

La película todavía no ha empezado, podemos comprar palomitas.

¿Todavía no sabes qué vas a estudiar en la universidad?

The most frequent mistake English speakers make with 'todavía' is confusing it with 'ya'. This is because 'yet' can be translated by both depending on the sentence type. In a question like 'Have you finished yet?', Spanish uses 'ya' ('¿Ya has terminado?'). However, in a negative answer like 'Not yet', Spanish uses 'todavía' ('Todavía no'). Learning this 'Question = Ya / Negative = Todavía' rule is the first step to avoiding errors.

The 'Ya' vs. 'Todavía' Trap: Don't use 'todavía' for 'already'. 'I already ate' is 'Ya comí', not 'Todavía comí'.

Incorrecto: No he terminado ya. (Correcto: Todavía no he terminado).

Another common error is the placement of 'no'. In English, we say 'not yet', putting the negation first. In Spanish, while 'no todavía' is occasionally heard for specific emphasis, the standard and most natural way is 'todavía no'. Beginners often say 'no he terminado todavía', which is grammatically correct but less common than starting the sentence with 'todavía no'.

The Accent Mark Confusion: While 'todavía' always has an accent on the 'í', its synonym 'aún' (still) is often confused with 'aun' (even/including). 'Todavía' is safer because it doesn't have this spelling trap.

Incorrecto: Él todavía no ha llegado ya. (Redundant use of 'ya').

Learners also struggle with 'todavía' in comparative sentences. They might try to use 'incluso' where 'todavía' is more natural. For example, 'This is even more expensive' is 'Esto es todavía más caro'. While 'incluso más caro' is possible, 'todavía' is the idiomatic choice for emphasizing a degree of difference. Finally, avoid using 'todavía' to mean 'still' in the sense of 'motionless' (quieto/inmóvil). 'Stay still' is 'Quédate quieto', not 'Quédate todavía'.

False Friend: Still (Motionless): 'Todavía' only refers to time or degree, never to physical lack of movement.

Incorrecto: El agua está todavía (meaning the water is not moving). Correcto: El agua está quieta.

No digas todavía que no, piénsalo un poco más.

¿Todavía no has visto esa película? Es un clásico.

The most direct synonym for 'todavía' is 'aún'. In most contexts, they are interchangeable. However, 'aún' is slightly more formal and is favored in literature and formal journalism. A key difference is that 'aún' requires an accent mark when it means 'still/yet', but loses it ('aun') when it means 'even/including'. 'Todavía' is more stable and common in spoken Spanish across all regions. Let's look at how it compares to other temporal markers.

Todavía vs. Aún: 'Todavía' is the everyday word. 'Aún' is the 'fancy' version. Both mean 'still'.

Aún no ha llegado el invierno. (Same as: Todavía no ha llegado).

Another related word is 'inclusive' or 'incluso', which means 'even'. While 'todavía' can mean 'even' in comparatives ('todavía más'), 'incluso' is used to include unexpected items in a list: 'Todos vinieron, incluso Juan' (Everyone came, even Juan). You cannot use 'todavía' in that sense. There is also 'ya', which is the opposite of 'todavía' in terms of state change. 'Ya' indicates that something has already happened or is happening now, whereas 'todavía' indicates that something is still happening or hasn't happened yet.

Todavía vs. Ya: 'Todavía' = Continuity. 'Ya' = Change. 'Todavía llueve' (It's still raining) vs 'Ya no llueve' (It's not raining anymore).

Él es todavía más alto que su hermano mayor.

Finally, consider 'siempre' (always). While 'siempre' indicates an infinite or habitual duration, 'todavía' focuses on the duration up to the present moment, often with the implication that it might change. 'Siempre vivo aquí' implies a permanent state; 'Todavía vivo aquí' implies that despite the passage of time or expectations of moving, I am still here. Understanding these subtle differences in temporal adverbs will greatly enhance your ability to describe the world in Spanish.

Todavía vs. Siempre: 'Siempre' is 'always'. 'Todavía' is 'still'. One is about frequency, the other about persistence.

¿Todavía estás con ese problema? Pensé que lo habías resuelto.

La tienda todavía está abierta, pero cierra pronto.

No es tarde, todavía podemos llegar a tiempo al cine.

小贴士

Placement is Key

Always place 'todavía' before 'no' when you want to say 'not yet'. Saying 'no todavía' is a common beginner mistake that sounds like a literal translation from English.

The 'Ya' Contrast

To master 'todavía', you must master 'ya'. Think of 'todavía' as 'the state continues' and 'ya' as 'the state has changed'. This mental model will solve 90% of your usage doubts.

Sound Natural

Use 'todavía más' instead of 'muy' when you want to emphasize a comparison. 'Es todavía más caro' sounds much more native than 'Es muy más caro' (which is actually incorrect).

Formal vs Informal

In your WhatsApp messages, use 'todavía'. In your university essays, try using 'aún' to demonstrate a higher register of Spanish vocabulary.

Catch the 'í'

Spanish speakers often speak fast. Listen for the sharp 'í' sound at the end of the word to identify 'todavía' in rapid conversation.

Song Lyrics

If you hear 'todavía' in a song, it's almost certainly about someone who 'still' loves their ex. It's the ultimate word for romantic nostalgia in the Hispanic world.

Visual Link

Imagine a clock with hands that keep spinning. That is 'todavía'. Now imagine the clock stopping. That change is 'ya'.

Not for Movement

Never use 'todavía' to mean 'stand still'. Use 'quieto'. 'Todavía' is only for time and degree, never for physical position.

Subjunctive Trigger

When using 'aunque' (although) with 'todavía', you will often need the subjunctive if the action hasn't happened yet. 'Aunque todavía no lo sepa...'

Common Answer

You can use 'Todavía no' as a standalone answer to almost any question about completion. It's polite, clear, and very common.

10 个问题

In most cases, they are identical in meaning. 'Todavía' is more common in speech, while 'aún' is more formal. 'Aún' also has a homophone 'aun' (without accent) which means 'even/including', making 'todavía' easier for learners to use without spelling errors.

Mostly, yes. However, in negative sentences it means 'yet' (todavía no). It can also mean 'even' when used with comparatives like 'todavía más' (even more). It never means 'still' in the sense of 'not moving'.

Usually before the verb: 'Todavía como'. In negative sentences, it goes before 'no': 'Todavía no como'. You can put it at the end for emphasis: '¿Estás aquí todavía?', but before the verb is the most standard position.

Yes, it works with all tenses. 'Todavía vivía allí' (I was still living there). 'Todavía no había llegado' (He hadn't arrived yet). It indicates continuity relative to the time being discussed.

It is grammatically possible but very rare. 'Todavía no' is the standard idiomatic way to say 'not yet' in Spanish. Using 'no todavía' might sound like a direct translation from English 'not yet' and can feel unnatural.

You say 'todavía mejor'. This is a very common way to use 'todavía' as an intensifier for comparative adjectives. You can also say 'aún mejor'.

No, 'todavía' is an adverb. Adverbs in Spanish are invariable, meaning they never change their form to match gender or number. It is always 'todavía'.

In Spanish, '¿Ya has terminado?' (Have you finished already/yet?) is the standard way to ask if an action is complete. '¿Todavía no has terminado?' is used if you expected them to be done and they aren't.

This is an idiomatic expression meaning 'even so' or 'nevertheless'. It's used to introduce a statement that contrasts with what was just said. It's a B2/C1 level phrase.

Yes, the accent on the 'í' is mandatory. It marks the stress on the third syllable and distinguishes the word's pronunciation. Without the accent, it would be pronounced differently and would be spelled incorrectly.
