Morphology

doctoral + dissertation

The meaning is directly and compositionally derived from 'doctoral' (relating to a doctorate) and 'dissertation' (a detailed written work for an academic degree); together they clearly indicate the lengthy formal research submitted for a doctoral degree. This compositional pattern is common cross-linguistically (e.g., Spanish 'tesis doctoral'), so a B1 learner who knows both constituents will readily understand the MWE.

Etymology

Doctoral dissertation comes from two parts: doctoral (about a 'doctor' degree) and dissertation (an old word for a long, formal 'discussion'). Picture a student writing a long, careful 'discussion' of research to show they deserve the doctorate, so the phrase means the long, formal research paper a student hands in to get a doctoral degree.
