The Full Form of Ph.D. is Doctor of Philosophy.

PhD is short for Doctor of Philosophy. This is an academic or professional degree that, in most countries, qualifies the degree holder to teach their chosen subject at university level or to work in a specialized position in their chosen field.

The word ‘philosophy’ comes from the Ancient Greek philosophia, literally translated as ‘love of wisdom’. It originally signified an individual who had achieved a comprehensive general education in the fundamental issues of the present world. Today, the Doctor of Philosophy still requires a love of wisdom but applies to individuals who have pursued knowledge in a much more specialized field.
