How to say "associate" in Japanese

Choosing the right word
  • 副ふくCommon
    noun, prefixCovers the title-like 'associate' meaning a deputy or assistant — the sense of 'vice-' or 'sub-'. As a prefix-like element it marks a subordinate, number-two position rather than a person.
  • 準じゅんCommon
    prefixCovers the 'associate' that means quasi- or semi- — a status that falls short of the full thing. It works as a prefix-like element expressing such partial standing, not as a word for a person.
  • 次席じせきCommon
    no-adjectiveA noun for the person next in rank — the junior, assistant position immediately after another's within a ranked order; its 'associate' is this junior-rank sense, not a companion or coworker.
  • 仲間なかまJLPT N3approx.Common
    nounCovers the person sense of 'associate' as a companion, fellow, or mate — someone in the same group or sharing the same activity; the feel is warm and personal, as with friends.
    田中たなかさんは父ちちのつり仲間なかまの一人ひとりだ。↗
    Mr. Tanaka is one of my father's fishing companions.
  • 同僚どうりょうJLPT N3approx.Common
    nounCovers the person sense of 'associate' as a coworker or colleague — someone who works alongside you at the same organization; the tie is professional, so it suits workplace settings.
    私の同僚どうりょうは報告書ほうこくしょを改かいざんした。↗
    My colleague doctored the report.

For people, use 仲間 for companions and 同僚 for coworkers; for the 'associate' of rank and status, 副 and 準 work as prefixes and 次席 names the person next in rank.
