PhD Full Form: Doctor of Philosophy Guide

The full form of PhD is Doctor of Philosophy, the highest postgraduate academic degree awarded for original research. Literally meaning “love of wisdom,” the term encompasses study across all disciplines, not just philosophy. Pursuing a PhD involves rigorous work—developing a research proposal, conducting authentic investigations, and writing a thesis over a typical span of 3–6 years. Universities in India and abroad require candidates to hold at least a master’s degree and often clear national entrance exams. Completing a PhD builds deep expertise and opens doors in academia, research, and advanced professional roles.
