How to Pronounce Sulci

Sulci is pronounced SUL-sy, with the stress on the first syllable. Think of it like saying "SULL" (rhymes with "bull") followed by "see." The 'c' is soft, so it sounds like an 's' rather than a hard 'k' sound.

The singular form is 'sulcus' (pronounced SUL-kus). Sulci is the Latin plural, so when doctors talk about one groove on the brain, they say sulcus, and when they talk about multiple grooves, they say sulci.

Sulci are the grooves or furrows you see on the brain's surface. A simpler way to think of it is like the wrinkles or creases on the brain—they're the dips between the raised folds (called gyri).

Sulci comes from Latin, where 'sulcus' originally meant a furrow or groove in the earth (like a plow would make). Scientists borrowed this word to describe the similar-looking grooves on the brain's surface.

A common mistake is saying it as "SUL-ky" (with a 'k' sound at the end) or stressing the second syllable like "sul-SY." Remember: it's SUL-sy with the stress firmly on that first syllable.

Sulci has two syllables: SUL-ci. The first syllable (SUL) is stressed and short, and the second syllable (ci) is quick and unstressed.

The word 'sulcus' (the singular form) shares the same Latin root. You might also hear 'sulcate,' which is an adjective meaning 'grooved' or 'furrowed'—it describes something that has sulci.

Sure! You could say: "The sulci on the brain's surface help increase the area of the cerebral cortex." This shows how sulci are the grooves that work alongside the raised folds (gyri) to create the brain's wrinkled appearance.
