incompetente
/inkompeˈtente/ · B2 · adj
incompetent
🤦 in- (not) + competente (able to compete/fit the job) = not up to the task
Spanish incompetente comes from Latin incompetens: in- (not) + competens (suitable, fitting). Link it to English competent: add the in- prefix and you get the opposite, someone not suited to do the job.
