Sense: adjective/1

Doctoral is the precise adjective for anything connected to a doctorate — the highest university degree. Postgraduate is broader: it covers all study after a bachelor's degree, including master's and doctoral levels. PhD-level is a more informal, job-description term that emphasises the depth of expertise required, not the academic program itself. Doctorate is a noun, though it sometimes appears before a noun as a modifier (e.g., 'doctorate degree'); in formal academic writing, doctoral is preferred. For example, you join a 'doctoral program' (not a 'doctorate program') and submit a 'doctoral thesis' (not a 'doctorate thesis').

Etymology

LatinEnglish

Doctoral comes from the Latin word doctor, meaning 'teacher.' In medieval Europe, a doctor was someone qualified to teach at a university. English added the suffix -al ('relating to') to form doctoral, which first appeared in the 1600s to describe the highest academic degree — originally one that gave the holder the right to teach.
