How to say "Appropriate" in Japanese

When translating "appropriate" into Japanese, you must choose carefully between 妥当 and 相応しい. In Japanese, 妥当 (だとう (datou)) is typically associated with "appropriate, valid, reasonable" (Syllabus Level: N2) and represents Used to describe an opinion, judgment, method, or decision as sensible, fair, and suitable under the circumstances. Often used with だ/です.. On the other hand, 相応しい (ふさわしい (fusawashii)) maps to "appropriate, suitable, fitting" (Syllabus Level: N2) and represents Describes something that is well-matched or appropriate for a particular situation, person, or purpose. Often used with a noun + に相応しい.. A literal translation of "appropriate" can often sound unnatural to native Japanese speakers if mixed up!
