cooperated
- 1Simple past and past participle of cooperate.
Local farmers cooperated to share equipment during the harvest.
Both governments have cooperated closely on the new trade agreement.
Note
One regular -ed form does double duty: they cooperated is the simple past, they have cooperated the perfect. Most uses are intransitive (people cooperate with each other, or on a project), so the form rarely turns passive. The exception is a piece of jargon about witnesses, where cooperate takes an object: a witness who has been cooperated has been turned into a cooperating one, and only there does a passive make sense.
