Desde

The Portuguese preposition desde is a foundational element of the language, primarily used to indicate the starting point of an action, state, or physical distance. For English speakers, it most commonly translates to 'since' when referring to time and 'from' when referring to space or a sequence. However, the nuance of desde lies in its ability to bridge the past and the present seamlessly. In Portuguese, when you use desde to describe an action that started in the past and is still happening, you typically use the present tense, which is a significant departure from the English present perfect construction. For instance, while an English speaker says 'I have lived here since 2010,' a Portuguese speaker says 'Moro aqui desde 2010.' This structural difference is one of the first hurdles for learners, as it requires a shift in how one perceives the flow of time within a sentence. The word itself is versatile, appearing in casual daily conversations, formal academic writing, and legal documents with equal frequency. It establishes a clear boundary or inception point, allowing the speaker to provide context for the duration or extent of a situation. Beyond time, desde is used to describe physical spans. If you are traveling from the north to the south, you might say 'viajei desde o norte,' emphasizing the origin of your journey. This spatial application is less frequent than the temporal one but remains a vital part of the word's functional range. In the context of European Portuguese versus Brazilian Portuguese, the usage remains remarkably consistent, though the surrounding syntax or preferred synonyms might vary slightly. Understanding desde is not just about learning a translation; it is about understanding the Portuguese concept of continuity. It is a word that looks backward to define the present. Whether you are discussing your professional history, your personal habits, or the history of a nation, desde provides the necessary temporal anchor.

Temporal Origin

Used to mark the specific moment in time when an ongoing action began. Example: 'Desde ontem' (Since yesterday).

Spatial Origin

Used to indicate the starting point of a physical distance or path. Example: 'Desde a entrada até ao fundo' (From the entrance to the back).

Logical Conjunction

When paired with 'que', it forms 'desde que', meaning 'since' (causal/temporal) or 'as long as' (conditional). Example: 'Desde que chegaste, tudo mudou' (Since you arrived, everything changed).

Mastering the use of desde requires an understanding of its grammatical placement and the tenses that typically accompany it. In its most basic form, desde is followed by a noun or a specific time marker. This is straightforward: 'desde a semana passada' (since last week), 'desde o meio-dia' (since noon), or 'desde a infância' (since childhood). When using desde to indicate a starting point in time for an action that continues into the present, the verb must be in the present indicative. This is a major point of confusion for English speakers. In English, we use the present perfect ('I have been waiting'). In Portuguese, you simply say 'Estou à espera desde as oito horas.' If the action was completed in the past but you are referencing its start, you might use the past tense: 'Ele foi o líder desde o primeiro dia.' Another critical construction is desde que. This phrase functions as a conjunction. When it means 'since' (temporal), it is followed by the indicative: 'Desde que ele partiu, não tivemos notícias.' However, when desde que is used to mean 'as long as' or 'provided that' (conditional), it triggers the subjunctive mood: 'Podes ir à festa, desde que faças os trabalhos de casa.' This dual nature of desde que is a hallmark of intermediate to advanced Portuguese. Furthermore, desde can be used in the correlative pair 'desde... até...' to define a range. This can be temporal ('desde as nove até às cinco') or spatial ('desde o Porto até Faro'). It is also common to see 'desde' paired with 'a partir de' in some contexts, though 'desde' implies a more continuous connection to the starting point. In Brazilian Portuguese, you might occasionally hear 'desde de', but this is considered grammatically incorrect and should be avoided in formal writing; the correct form is simply 'desde'. When referring to a specific date, no article is needed: 'desde 1500'. However, if the noun is feminine or masculine and requires an article, contraction occurs if applicable, though 'desde' does not contract with 'o' or 'a' like 'de' does. You write 'desde o dia' and 'desde a hora'. This lack of contraction makes it easier to remember than other prepositions. In summary, use desde to anchor your sentences in a specific origin, and pay close attention to whether you are expressing a simple time marker or a conditional requirement.

Temporal Marker

Placed before dates, times, or events. Example: 'Desde o Natal'.

Range Indicator

Used with 'até' to show a span. Example: 'Desde a infância até à idade adulta'.

Conditional Conjunction

'Desde que' + Subjunctive. Example: 'Desde que estudes, passarás'.

In the real world, desde is omnipresent. You will hear it in the first few minutes of any news broadcast: 'Desde as primeiras horas da manhã, manifestantes reuniram-se...' (Since the early hours of the morning, protesters gathered...). It is the language of reporting and history. When reading a biography of a famous Portuguese figure like Fernando Pessoa or Amália Rodrigues, you will inevitably encounter desde to describe the arc of their lives. In daily social interactions, it is used to express impatience or endurance: 'Estou aqui à tua espera desde as seis!' (I've been here waiting for you since six!). It is also common in commercial settings. Signs in shop windows might say 'Aberto desde 1920' (Open since 1920), using the word to establish a sense of tradition and reliability. In the workplace, your boss might ask, 'Desde quando é que este relatório está pronto?' (Since when has this report been ready?). In the realm of music, particularly Fado or Brazilian Bossa Nova, desde often introduces a sense of longing (saudade) for a time or person lost: 'Desde que te foste embora...' (Since you went away...). It is a word that carries emotional weight because it connects the current state of the speaker to a definitive point of change. In legal and bureaucratic contexts, desde is used to define the effective dates of laws or contracts: 'Esta lei entra em vigor desde a data da sua publicação.' Even in sports commentary, you'll hear it: 'O Benfica não perdia em casa desde o ano passado.' The word is so ingrained that it often loses its emphasis, becoming a quick phonetic bridge between the subject and the time marker. In Lisbon, you might hear it pronounced with a very soft 's', almost like 'dezh-de', while in other regions, the 's' might be sharper. Regardless of the accent, the function remains the same. It is a word that provides the 'when' and the 'where' of the Portuguese experience, making it indispensable for anyone looking to achieve fluency. Whether you are listening to a podcast, watching a 'telenovela', or chatting with a neighbor, desde will be there, anchoring the conversation in time and space.

News & Media

Used to report ongoing events or historical context. 'Desde o início da crise...'

Business & Commerce

Used to establish longevity and trust. 'Desde 1950 ao seu serviço.'

The most frequent mistake English speakers make with desde is a direct result of 'interlanguage interference'—applying English grammatical rules to Portuguese. In English, we say 'I have been here for two hours' (duration) and 'I have been here since two o'clock' (starting point). In Portuguese, these are handled by two different words: há and desde. Learners often say 'Estou aqui desde duas horas' when they mean 'I have been here for two hours.' The correct way to express duration is 'Estou aqui há duas horas.' Use desde only when you are pointing to a specific moment on the calendar or clock. Another common error is the use of the past tense where the present is required. An English speaker might say 'Eu estive aqui desde as nove' (I was here since nine), but if they are still there, they must say 'Estou aqui desde as nove.' The past tense 'estive' implies the action is over, which contradicts the meaning of 'since' in an ongoing context. Furthermore, many students confuse desde with de. While both can mean 'from', de is a general preposition of origin ('Eu sou de Portugal'), whereas desde emphasizes the starting point of a range or a continuous state ('Viajei desde Portugal até à China'). Another trap is the phrase desde que. As mentioned previously, learners often forget to use the subjunctive when it means 'as long as'. Saying 'Vou contigo desde que tens dinheiro' is wrong; it should be 'desde que tenhas dinheiro'. Finally, in some regions of Brazil, you might hear the redundant 'desde de'. While you will be understood, it is a marker of non-standard speech and should be avoided in formal contexts. To avoid these mistakes, always ask yourself: 'Am I talking about a starting point or a total amount of time?' If it's a starting point, use desde. If it's a total amount of time, use há. Also, remember that 'desde' does not change for gender or number; it is an invariable preposition, which makes it one of the simpler words to spell and use correctly once the logic is mastered.

Confusion with 'Há'

Mistake: 'Desde dois anos' (Since two years). Correct: 'Há dois anos' (For two years) or 'Desde 2021'.

Tense Error

Mistake: 'Vivi aqui desde 2010' (if still living there). Correct: 'Moro aqui desde 2010'.

While desde is the most common way to say 'since', Portuguese offers several alternatives depending on the context and the desired level of formality. One of the closest synonyms is a partir de. While desde usually refers to the past leading up to the present, a partir de is often used for the future or to indicate a new starting point: 'A partir de amanhã, tudo será diferente' (From tomorrow on, everything will be different). It can also be used for space: 'A partir daqui, o caminho é difícil.' Another alternative is de, but as discussed, it is much more general and lacks the emphasis on continuity that desde provides. In more formal or literary contexts, you might see doravante, which means 'from now on' or 'henceforth'. For the phrase 'since then', you can use desde então or desde essa altura. If you want to say 'ever since', a more emphatic version is desde sempre, which implies that something has been true for as long as anyone can remember: 'Eles são amigos desde sempre.' When desde que is used as a causal conjunction (meaning 'since' or 'because'), synonyms include já que, visto que, or dado que. For example, 'Já que estás aqui, ajuda-me' is similar to 'Desde que estás aqui, ajuda-me,' though 'já que' is more common for expressing cause. In terms of spatial 'from', desde can sometimes be replaced by vindo de (coming from) if you want to emphasize the movement. Understanding these alternatives allows you to vary your vocabulary and sound more like a native speaker. For instance, using 'a partir de' when discussing a schedule sounds more natural than using 'desde'. 'O escritório está aberto a partir das nove' sounds more like a policy, whereas 'O escritório está aberto desde as nove' sounds like a statement of fact about today. By choosing the right word, you convey subtle differences in meaning that enrich your communication.

A partir de

Focuses on the start of a new period or future point. 'A partir de agora'.

Já que / Visto que

Used as causal alternatives to 'desde que'. 'Visto que não vieste, eu fui sozinho'.

Doravante

Formal term for 'from now on'. Used in legal or academic texts.
