Morphology
sinus + coronarius
This is a Latin anatomical compound: 'sinus' denotes a venous/vascular channel and 'coronarius' corresponds to 'coronary' (pertaining to the heart). A learner who knows both constituents can infer it is a venous channel associated with the heart, but the precise clinical function and specificity are technical and not fully predictable from general word meanings.
Etymology
Sinus coronarius comes from the Latin words sinus and coronarius, which mean 'bay' and 'crown'. The image is of a small bay or pocket around the heart where veins gather, so sinus coronarius refers to the short vessel that collects blood from the heart's veins and empties into the right atrium.
