Pronunciation[edit]

  2. partner or subordinate in an activity
  3. to the same degree
  4. (mathematics) of the opposite, of the counterpart; dual
    cokernel; codimension; cosine; counion; cointersection

Usage notes[edit]

  • With many terms, a hyphen (-) is used in British English (e.g. co-operate), which is omitted in informal American English (e.g. cooperate). In formal American English the second vowel would be decorated with a diaeresis (coöperate), although this usage is rare and somewhat fussy.
