💡

Comma Rule

If the connector starts the sentence, use a comma. If it's in the middle, you don't need one.
frontend.learn_grammar.from_rule: Clauses of Contrast, Purpose, and Reason
💡

Don't translate

Stop trying to translate the preposition from your native language. It will almost always be wrong.
frontend.learn_grammar.from_rule: Adjective + Preposition: Interested IN, Good AT, Afraid OF
💡

The 'if' rule

Always use 'if' or 'whether' for yes/no questions. Don't just start with the subject.

よくある質問 (6)

Yes, but it's more common in informal speech. In formal writing, use 'Since' or 'As'.
'So' is a result (I was tired, so I slept). 'So that' is a purpose (I study so that I can learn).
English prepositions are specific to the adjective. Using 'to' will sound unnatural.
There are hundreds, but focus on the top 50 first.
No, use 'for' for time amounts like 'two hours'.
'While' needs a verb (clause), 'during' needs a noun.
