=cooperate

co- (together) + oper (work) + -ate (verb) = 'to work together.' Fully transparent: when two parties cooperate, they are literally laboring side by side toward one aim. A secondary, everyday sense is 'to be cooperative' — to comply willingly when asked.

Usage Guide

Two prepositions: cooperate WITH someone, cooperate ON something. 'We cooperated with the police on the investigation.' The spelling is modern solid 'cooperate'; the older hyphenated 'co-operate / co-operation' still appears in British and formal texts.
