**Doctorate** → It is formed from "doctor" (from Latin *docere*, meaning to teach) and the suffix "-ate" (meaning to make or to become). The word "doctorate" refers to the degree that signifies one has become a teacher or expert in a particular field.
Think of someone who has 'become' ('-ate') a 'teacher' ('doctor') — that's why a doctorate is a degree that signifies expertise in a subject.
