Morphology

rectus + superior

The term is compositional from Latin anatomical roots: 'rectus' (a straight muscle) + 'superior' (upper), so a learner who knows the constituents can infer it refers to an upper/upper-positioned muscle. However, recognizing it specifically as the eye muscle that lifts the eyeball upward and inward (its precise anatomical function and site) requires domain knowledge, and the exact functional role is not fully predictable from the parts alone; similar Latin anatomical naming across languages may help but does not make the detailed meaning completely transparent.

Etymology

Rectus superior comes from the Latin words rectus meaning 'straight' and superior meaning 'upper', because this eye muscle sits on the top of the eyeball and pulls the eye up and a little in. So, rectus superior means the muscle that lifts the eye up and in.
