Morphology

rectus + inferior

The term is compositional in Latin-derived anatomical naming: 'rectus' = straight (muscle) and 'inferior' = lower, so a learner who knows those constituents can infer it refers to a lower/underneath straight muscle. However, the specific function as an extraocular muscle that turns the eyeball downward and toward the midline is technical and not fully predictable from the parts alone, so comprehension would be partial without domain knowledge.

Etymology

Rectus inferior comes from Latin words rectus ('straight') and inferior ('lower'). The muscle is the straight one under the eye that pulls the eyeball down and toward the middle, so the name tells what it does.
