Morphology

posttraumatic + amnesia

The phrase is compositionally built: 'posttraumatic' means occurring after a traumatic event and 'amnesia' means loss of memory, so the combined meaning—memory loss following trauma—is directly derivable from the parts. Although it is a medical term with specific temporal nuance, the logic is straightforward and cross-linguistically transparent, so a B1 learner who knows both constituents would understand it.

Etymology

Posttraumatic amnesia breaks into clear parts: post ('after'), traumatic ('caused by an injury'), and amnesia ('memory loss'). It creates the image of someone who cannot remember events that happen right after a trauma, so it means 'memory loss after the injury'.
