cooperar
/koopeˈɾaɾ/ · B1 · verb
to cooperate
🤝 co + operar = operate together, work jointly toward the same goal
From Latin cooperari: co- (together) + operari (to work). English cooperate is the same word, so just stretch it to four even beats: co-o-pe-RAR, with the stress on the final -rar like most Spanish infinitives.
