How to say "committee" in Japanese

• 委員会いいんかいCommon
  nounThe common word for a committee, and also for a commission, board, or panel: a body of members set up to deliberate on or handle a particular matter, at a company, school, or legislature.
  委員会いいんかいはその議案ぎあんを可決かけつした。↗

  The committee passed the bill.
• 委い
  noun (suffix)An abbreviation of 委員会, covering the same senses but less common on its own; for a committee in an ordinary sentence, 委員会 is the word to use.
• コミッティー
  nounA katakana rendering of the English 'committee'. It covers the same sense but is less common, and 委員会 already expresses the meaning, so there is seldom a need to reach for it.

For 'committee' in any ordinary sense, use 委員会, the common word (also 'commission', 'board', 'panel'); 委 is merely its abbreviation, and 「コミッティー」 a less common loanword — neither is usually what you want.
