trabajador
/tɾabaxaˈdoɾ/ · B1 · adj
hard-working
👷 trabajo (work) + -dor (doer) = one who works, hence hard-working
From trabajar (to work) plus the agent suffix -dor, like English -er in worker. The same suffix builds vendedor (seller) and jugador (player). As an adjective it means hard-working; as a noun, a worker.
