Morphology
sulcus + centralis
The term is compositionally built from 'sulcus' (a groove) and 'centralis' (Latin cognate of 'central'), so its meaning 'central groove' separating lobes is directly derivable from the constituents. Although technical and using Latin word order, the constituents are transparent and 'centralis' has clear cross-linguistic cognates (central/centrale/centrál/etc.), making the phrase predictable to a learner who knows the parts.
Etymology
Sulcus centralis comes from Latin: sulcus means 'groove' and centralis means 'central' or 'middle'. So sulcus centralis literally means the 'central groove' on the brain, the deep line that separates the front part from the part behind it, which is why it helps doctors find areas for movement and feeling.
