Pronunciation

Correct

sass

/sæs/

One syllable, rhymes with 'mass'. The official Sass documentation explicitly states it is pronounced as a word, not an acronym.

Common Mistake

S-A-S-S

/ɛs eɪ ɛs ɛs/

Spelling it out letter by letter is incorrect. The Sass documentation is explicit: it is a word, not an initialism.
