Morphology
The compound simply combines 'transcortical' (relating to pathways through the cortex) with 'aphasia' (loss of language), so the phrase denotes a language impairment related to cortical pathways. This adjectival + medical-noun formation is compositional and would be understandable to a B1 learner who knows both constituents, even if they lack detailed clinical knowledge.
Etymology
Transcortical aphasia comes from the parts trans- 'across', cortical 'brain's outer layer', and aphasia 'loss of speech'. The name gives the image of damage that crosses the brain's outer language areas, so people with this problem may have trouble speaking on their own but can often still 'repeat' words.
