PhD

Doctor of Philosophy - Wikipedia

The degree is abbreviated PhD (sometimes Ph.D. in the U.S.), from the Latin Philosophiae Doctor, pronounced as three separate letters (/piːeɪtʃˈdiː/, PEE-aych-DEE).^[9][10][11]

The abbreviation DPhil, from the English 'Doctor of Philosophy',^[12] is used by a small number of British and Commonwealth universities, including Oxford, formerly York, and Sussex,^[13] as the abbreviation for degrees from those institutions.^[14]

In the context of the Doctor of Philosophy and other similarly titled degrees, the term "philosophy" does not refer to the field or academic discipline of philosophy, but is used in a broader sense in accordance with its original Greek meaning, which is "love of wisdom."

In most of Europe, all fields (history, philosophy, social sciences, mathematics, and natural philosophy/sciences)^[8] other than theology, law, and medicine (the so-called professional, vocational, or technical curriculum) were traditionally known as philosophy, and in Germany and elsewhere in Europe the basic faculty of liberal arts was known as the "faculty of philosophy."
