How to say "Appropriate" in Japanese

When translating "appropriate" into Japanese, you must choose carefully between 妥当 and しかるべき. 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, しかるべき (しかるべき (shikarubeki)) maps to "appropriate, proper, due, right" (Syllabus Level: N2) and represents Describes something that is naturally or rightfully expected, or a place/person that is suitable. Often implies 'the one that should be'.. A literal translation of "appropriate" can often sound unnatural to native Japanese speakers if mixed up!
