Etymology: "Triconsonantal" is built directly from "tri-", meaning three, and "consonantal," the adjective from "consonant." Together they describe something made of three consonants, a combination that matters in languages like Arabic and Hebrew, where most words are built from a three-consonant root and vowels are layered around it to mark different meanings. The word is a plain compound, so its story lies in its parts. "Tri-" comes from Greek "treis," and "consonantal" traces back to the Latin "consonans," a sounding together, which is also the source of "consonant." The adjective describes the consonant sounds themselves rather than the letters on the page, which is why it is useful to linguists studying how sounds pattern within a word.
