Morphology
The constituents are largely compositional—'inferior' (lower), 'rectus' (a straight muscle) and 'muscle'—so a learner who knows these words can infer it refers to a lower/straight muscle. However, recognizing that this is specifically an extraocular muscle (in the eye) and understanding its precise function (downward and inward movement) requires anatomical knowledge and is not fully predictable from the parts, making the term only partially transparent.
Etymology
Inferior rectus muscle comes from words meaning inferior 'lower' and rectus 'straight'. The name shows its job: the straight muscle under the eye pulls the eye 'down' and 'in', so it controls looking 'down' and 'in'.
