わかります

The Japanese verb わかります (wakarimasu) is one of the most fundamental yet nuanced words a learner will encounter. At its core, it translates to "to understand," but its grammatical behavior and cultural implications differ significantly from its English counterpart. In English, "understand" is a transitive verb where a subject performs an action on an object (e.g., "I understand the lesson"). In Japanese, わかります functions more like an intransitive verb or a state-of-being, describing the condition where something has become clear or is known to the speaker. This is why the object of understanding is marked with the particle が (ga) rather than を (o).

Core Meaning

To be clear, to be understood, or to possess the knowledge/ability to comprehend a specific subject or situation.

Japanese speakers use this word in a vast array of contexts, from confirming directions to expressing empathy. Because Japanese culture values indirectness and social harmony, saying "wakarimasu" often signals not just cognitive comprehension, but also social alignment. For instance, in a business setting, saying "Wakarimashita" (the past tense) doesn't just mean "I understood the words you said," but rather "I have received your instruction and will comply." This performative aspect of the verb is crucial for navigating Japanese social hierarchies. Whether you are a student listening to a teacher or a traveler asking for the way to the station, this word serves as the bridge of mutual recognition.

Usage Frequency

High. It is found in nearly every daily conversation, from formal business meetings to casual chats among friends.

Furthermore, the word encompasses varying levels of depth. It can mean a superficial recognition of a fact, or a deep, intuitive grasp of a complex emotion. In the CEFR A2 level, learners are expected to use it for basic needs, such as understanding simple instructions or general information in familiar contexts. As you progress, you will see it used in the potential sense (to be able to understand) and even in the passive sense in more academic writing. Understanding the etymology—from the verb 'wakaru' meaning 'to divide'—helps clarify the concept: to understand something is to be able to 'divide' or 'distinguish' its components from one another.

Cultural Nuance

In Japan, admitting you 'don't understand' (wakarimasen) is perfectly acceptable and often encouraged to avoid mistakes, whereas in some Western cultures, people might pretend to understand to save face.

Constructing sentences with わかります requires a shift in how you think about subjects and objects. In English, we say "I understand Japanese." In Japanese, the structure is closer to "As for me, Japanese is understandable." This is why we use the topic marker は (wa) for the person and the subject marker が (ga) for the thing being understood. If the topic (the person) is obvious from context, it is almost always omitted, leaving just '[Subject] ga wakarimasu.'

Standard Pattern

[Person] は [Thing] が わかります。 (Watashi wa nihongo ga wakarimasu.)

To modify the degree of understanding, adverbs are placed before the verb. Common adverbs include よく (yoku - well), だいたい (daitai - mostly/roughly), すこし (sukoshi - a little), and あまり (amari - not very much). When using negative adverbs like 'amari' or 'zenzen' (not at all), the verb must be in its negative form: わかりません (wakarimasen). This flexibility allows you to precisely communicate your level of comprehension, which is vital in learning environments.

Degree Modifiers

よくわかります (Understand well), すこしわかります (Understand a little), ぜんぜんわかりません (Don't understand at all).

Another important aspect is the tense. わかります is present/future tense, meaning you currently understand or will understand. わかりました (wakarimashita) is the past tense, used when a lightbulb goes off in your head or when you are acknowledging a command. In English, we often say "I understand" when someone gives us an order, but in Japanese, "Wakarimashita" is more common because the act of understanding (the processing of the information) has just been completed.

Tense Distinction

Present: わかります (General state). Past: わかりました (Moment of realization or agreement).

You will hear わかります in almost every interaction in Japan. In the classroom, teachers frequently ask 「わかりますか？」 (Wakarimasu ka? - Do you understand?) to check students' progress. In the workplace, subordinates use 「わかりました」 (Wakarimashita) or the more formal 「承知いたしました」 (Shouchi itashimashita) to confirm they have understood a task. Even in casual settings, friends use the short form 「わかる！」 (Wakaru!) as a way of saying "I totally get you!" or "I feel the same way!" this empathetic usage is very common among younger generations.

Daily Life

Train announcements, store clerks explaining a product, and friends discussing their feelings.

In media, such as anime or drama, characters often use 「わかった」 (Wakatta) to show they've solved a mystery or agreed to a plan. In news broadcasts, reporters might use it when summarizing a situation: 「〜ということがわかりました」 (...to iu koto ga wakarimashita - It has become clear that...). This usage shifts the focus from personal understanding to the objective discovery of facts. When you are at a restaurant and the waiter explains the menu, your response should be a polite 「わかりました、ありがとうございます」.

Professional Context

Used to acknowledge instructions, though Keigo (honorifics) like 'Shouchi-shimashita' is preferred in very formal settings.

One interesting place you'll hear it is in the form of a question to oneself. People often say 「あ、わかった！」 (A, wakatta!) when they find a lost item or remember a forgotten name. In this sense, it means "I've found it!" or "I've got it!". It is also used in customer service settings where a clerk might say 「かしこまりました」 (Kashikomarimashita), which is a very humble version of "Wakarimashita," indicating they will fulfill your request with the utmost respect.

The most common mistake for English speakers is using the particle を (o). Because we say "I understand *the* book," it is tempting to say "Hon o wakarimasu." However, as mentioned, わかります is an intransitive verb in Japanese logic. The thing being understood is the subject that "is clear." Therefore, you must use が (ga). Using 'o' is a major grammatical error that sounds very unnatural to native ears.

Mistake 1: Wrong Particle

Incorrect: 日本語をわかります (Nihongo o wakarimasu). Correct: 日本語がわかります (Nihongo ga wakarimasu).

Another frequent error is confusing わかります with 知っています (shitte imasu - to know). While they overlap, they are not interchangeable. 'Wakarimasu' implies a process of comprehension or reasoning. 'Shitte imasu' implies simply possessing information. For example, you 'know' (shitte imasu) a person's phone number, but you 'understand' (wakarimasu) a complex math problem. If you say "Tanaka-san o wakarimasu," it sounds like you understand his personality or soul, whereas "Tanaka-san o shitte imasu" simply means you know who he is.

Mistake 2: Knowing vs. Understanding

Use 'Shitte imasu' for facts/data. Use 'Wakarimasu' for comprehension/logic/feelings.

Finally, learners often overuse the present tense when the past tense is required. If a teacher explains a grammar point and asks if you get it, answering "Wakarimasu" (present) sounds like you are making a general statement about your ability. Answering "Wakarimashita" (past) indicates that the specific explanation they just gave has successfully entered your brain. It is the difference between "I am understanding" and "I have understood."

While わかります is the go-to word for general understanding, Japanese offers many alternatives depending on the level of formality and the specific type of comprehension. For example, 理解する (rikai suru) is a more formal, academic word for "to comprehend." You would see this in textbooks or use it when discussing a deep understanding of a philosophy or a complex system. It is a Suru-verb, meaning it behaves differently grammatically and often takes the particle 'o'.

Wakarimasu vs. Rikai suru

'Wakarimasu' is daily/intuitive. 'Rikai suru' is formal/intellectual.

In a business context, 承知する (shouchi suru) and 了解する (ryoukai suru) are common. 'Shouchi' is very polite and used when accepting a request or acknowledging information from a superior. 'Ryoukai' is more commonly used among colleagues or by a superior to a subordinate; it has a military-like nuance of "Roger that." Using 'ryoukai' to your boss might come off as too casual or slightly rude, so be careful with the social hierarchy!

Business Alternatives

承知いたしました (Shouchi itashimashita - Very polite), 了解です (Ryoukai desu - Casual/Colleague).

If you want to say you've "grasped" the essence of something or "mastered" a concept, you might use 把握する (haaku suru). This word is often used for grasping a situation or data. For casual agreement, simply saying 「なるほど」 (Naruhodo), which means "I see" or "Indeed," is a great way to show you understand what someone is saying without using a verb at all. Learning these alternatives will make your Japanese sound more natural and contextually appropriate.
