Morphology

transversus + abdominis

The term is a compositional anatomical name: 'transversus' means oriented transversely and 'abdominis' denotes the abdomen, so together they indicate a transverse muscle of the abdominal wall. Anatomical naming follows predictable compounding patterns (and many languages use the same logic), so a learner who knows the constituent meanings can infer the MWE's sense.

Etymology

Transversus abdominis comes from Latin words: transversus meaning 'across' and abdominis meaning 'of the abdomen'. The name fits the muscle's image — a flat band that runs like a belt across the front and sides of the belly, so it squeezes the inside organs and helps 'support the spine' and keep the body stable.
