Morphology
The meaning is directly and transparently derived from 'pectoral' (chest-related) + 'girdle' (an encircling skeletal or ringlike part): together they denote a chest-related encircling bony structure. Although anatomical and somewhat technical, the composition follows regular English patterns so a B1 learner who knows both constituents can infer the intended meaning.
Etymology
The noun pectoral girdle combines pectoral meaning 'chest' and girdle meaning 'belt'. Imagine a belt around the chest that holds the arms in place. That's why it names the bones that connect the arms, wings, or fins to the body.
