Morphology
sinus + rectus
The term is compositionally built from 'sinus' (venous channel) plus 'rectus' (Latin for 'straight'), so the sense 'straight sinus' follows directly for someone who knows both constituents. However, 'rectus' is a Latin/technical adjective not common in general English and the whole phrase is specialist anatomical jargon, so an average B1 learner would likely not recognise or confidently infer the meaning without prior exposure.
Etymology
Sinus rectus comes from Latin: sinus means 'channel' and rectus means 'straight'. It is a straight blood channel that sits where two coverings of the brain meet, so the name gives a simple picture of its shape and role.
