the.com/disciple

means A follower who commits to learning from and imitating a teacher or leader, often absorbing their whole way of life, not just their facts.

from From Latin discipulus, 'learner' or 'pupil,' built from discere, 'to learn' — the same root that gives us 'discipline.' That connection is telling: in the old sense, discipline wasn't punishment, it was simply what a disciple did — the practice and training of one devoted to learning.
