Morphology

pyriform + lobe

The term directly combines 'pyriform' (pear-shaped) with 'lobe' (a projecting part), so a learner who knows both constituents can infer it denotes a pear-shaped anatomical portion. However, the specific identification as a brain region involved in olfaction (rhinencephalon) and its technical medical sense are specialized and not fully predictable from the parts, making the expression only partly transparent to a B1 learner.

Etymology

Pyriform lobe gets its name from a simple picture: pyriform means 'pear-shaped' and lobe means a part of the brain. It sits near the nose and helps the 'sense of smell', so the name shows it is a pear-shaped brain area used for smelling.
