Difference Between “Co-operate” OR “Cooperate”

Definition of Co-operate

"Co-operate", with a hyphen, emphasizes the aspect of operating together with one or more parties. It signifies a deliberate partnership or collaboration to achieve a common objective.

Definition of Cooperate

"Cooperate", written without a hyphen, refers to the act of working in tandem with others for a mutual benefit or to achieve a shared goal. It is the more commonly accepted spelling in contemporary usage.

Origin of Co-operate

  • “Co-operate” has its roots in the early 17th century, derived from the Latin co- meaning “together” and operari meaning “to work”. The hyphenated form has been used historically to emphasize the prefix co-.

Origin of Cooperate

  • “Cooperate” follows the same etymological path as “co-operate”, but the evolution of language and preferences for less punctuated words have made this the preferred form in modern English.


  • Both terms are pronounced similarly: /kəʊˈɒpəreɪt/ in British English and /koʊˈɑːpəˌreɪt/ in American English, though the hyphen in “co-operate” does not affect pronunciation.

Comparing Co-operate and Cooperate
