IPA: /ˈpjuːpɪlɪdʒ/
KK: /ˈpjuːpɪlɪdʒ/
The condition or time when someone is a student or learner, especially in a school or educational setting.
During his pupilage, he learned many important skills that would help him in his career.
Pupilage is derived from 'pupil' (from Latin 'pupillus', meaning a minor or ward) and the suffix '-age' (meaning a state or condition). The term 'pupilage' refers to the state or condition of being a pupil or student.
Think of a 'pupil' as a student and '-age' indicating a state — so 'pupilage' means the state of being a student.
