IPA: /ˈkoʊtʃəbl/
KK: /ˈkoʊtʃəbl/
Able to learn and improve through guidance and instruction from a coach or mentor.
She is very coachable and always eager to learn new skills.
Coachable is formed from "coach" (from Old French *cochier*, meaning to drive or transport) and "-able" (meaning capable of). The word "coachable" means capable of being guided or trained by a coach.
Think of someone who is 'capable of being guided' — 'coach' refers to the person who trains, and '-able' means capable.
