Is there any difference between adept at and adept in? Should you believe it utterly depends on the context, I would be grateful if you would at least provide a brief explanation of how it depends.

As seen in this Google Ngram search, adept in is the more archaic usage, while adept at is more modern.

Furthermore, adept was historically used as a noun, as in: "He is an adept in the game of chess." Currently, adept is more commonly used as an adjective, as in: "He is adept at the game of chess."


According to the Oxford Collocations Dictionary for Sudents, you supposed to use "adept at"

adept adj. • VERBS be, seem | become • ADV extremely, highly, very | quite • PREP. at "He was highly adept at avoiding trouble."

  • The other answer is correct: "adept at" is not wrong, but it is not the only right usage, either. Jun 19, 2015 at 22:00
  • Yes. You need to be careful; non-entry in a dictionary does not mean* that a word or usage is necessarily incorrect. Dictionaries aren't identical. Even OED gives this caveat* about the portion of the lexicon it gives definitions for. Aug 7, 2016 at 21:08
