• Synonym明瞭めいりょうWrittenWritten/formal Sino-Japanese word for clear and plain, as in 「明瞭な発音」 or 「簡単明瞭」. More formal than 「はっきり」, and it never suggests speaking frankly or bluntly.
• Synonym判然はんぜんWrittenA written/formal word for things being clearly distinguishable or a judgment being clear; often in the negative 「判然としない」. In everyday speech, just say 「はっきりしない」.
• SynonymくっきりCasualColloquial mimetic word for outlines and edges standing out sharply, as in 「富士山がくっきり見える」; also for marked differences. 「はっきり」 also covers attitudes, voices and wording.
• RelatedありありCasualColloquial word for feelings or images showing through plainly, as in 「不満がありありと見える」. Focuses on emotions showing on the face or something imagined appearing vividly.
• RelatedしかとWrittenSomewhat literary and old-fashioned, meaning certainly and firmly, as in 「しかと承った」 or 「しかと見届ける」. Carries a more solemn tone than 「はっきり」.
• RelatedまざまざCasualColloquial: vividly, as if right before your eyes, as in 「まざまざと思い出す」 or 「力の差をまざまざと見せつけられる」. Often carries a sense of something you would rather not face.
• Antonym曖昧あいまいNeutralA common everyday word for vague or ambiguous, as in 「曖昧な返事」 or 「曖昧にする」. The everyday opposite of the clear, definite 「はっきり」.
• AntonymぼんやりCasualColloquial word for things looking hazy or indistinct, as in 「ぼんやり見える」; also absentminded or spacing out. Opposes 「はっきり」 for unclear sight or hazy awareness.

For clear or definite, 「はっきり」 is the default. Use 「明瞭」 in formal writing, 「くっきり」 for sharp outlines, and 「まざまざ」 for something vividly before your eyes. For vague or ambiguous say 「曖昧」, for hazy or indistinct 「ぼんやり」.
