あしたはだれと会いますか。
- Who will you meet tomorrow?

あしたはだれと会いますか。 meaning: "Who will you meet tomorrow?"

The sentence follows a Subject-Object-Verb structure, although the subject is often omitted in Japanese when it's clear from the context. In this case, the implied subject is "you." ⚫︎The sentence structure can be broken down as follows: あした - Tomorrow (time) は - Topic marker だれ - Who (object) と - With (particle) 会いますか - Will meet (verb + question marker)

Particles are essential in Japanese grammar, indicating the grammatical function of words in a sentence. ⚫︎は (wa): ⚫︎This is the topic marker. It indicates what the sentence is about. In this sentence, あした is the topic, meaning the sentence is about "tomorrow." ⚫︎It is placed after the topic. ⚫︎と (to): ⚫︎This particle means "with" and indicates who you are meeting. ⚫︎It is used with a person or a group of people. ⚫︎It is placed after the person (or だれ in this case).

The particle か (ka) at the end of a sentence turns it into a question. ⚫︎It is added directly to the end of the verb. ⚫︎In this sentence, it's added to 会います, which becomes 会いますか ("Will you meet?").

The verb 会います is in the present/future tense. In Japanese, the same verb form can be used for both. ⚫︎会う (au) - to meet (dictionary form). ⚫︎会います (aimasu) - meet/will meet (polite form, present/future tense). ⚫︎This is the polite form. ⚫︎It is formed by changing the final -u of the dictionary form to -imasu. ⚫︎The meaning depends on the context and can be either "meet" (present) or "will meet" (future).
