Morphology

doctor + of + philosophy

The phrase is transparently built from its parts: 'doctor' (a holder of a doctoral degree) + 'of' + 'philosophy' (a field), so a learner who knows the constituents will infer it denotes a doctor in the field of philosophy (i.e., a doctoral degree). Although the formal use 'Doctor of Philosophy' (PhD) can function as a broad academic title across disciplines in English, the compositional structure is clear and follows common patterns found in many languages, making it readily understandable to a B1 learner.

Etymology

Doctor of Philosophy comes from old universities where doctor meant a respected 'teacher' and philosophy meant 'love of wisdom' or all serious learning. So the title originally meant a top teacher of wide knowledge, and today it is used as the name for the highest 'research degree' in many fields.
