Expressions

Use はずだ for expected outcomes and べきだ for moral obligations or advice.

Use かもしれない for uncertain possibilities and だろう for probable assumptions. だろう is often used in casual conversations, while かもしれない is more neutral.

Use ことがある for general or recurring actions, and たことがある for completed experiences. The key difference lies in the tense and aspect of the action.

Use ないで to request or command someone not to do something. Use なくて to state a reason or condition. For example, '食べないで' (tabenai de) means 'don't eat', while '食べなくて' (tabenakute) means 'because I didn't eat'.

Use らしい to describe something based on appearance or hearsay. Use ようだ to describe something based on evidence or observation. Both convey 'seems' or 'appears to be'.

Use そうだ for hearsay when reporting what someone said, and for appearance when describing how something seems. The context and surrounding words will help disambiguate. Practice active listening to improve understanding.

Use ために for controllable actions, and ように for uncontrollable or desired outcomes. ために implies a direct intention, while ように implies a hope or wish.

Use ようにする for habitual effort and ことにする for making a decision. ようにする implies continuous action, while ことにする is a one-time choice.
