Etymology: "Diphthongated" is a form of the verb "diphthongate," built from "diphthong" plus the verbal ending "-ate." "Diphthong" comes from Greek "diphthongos," meaning "having two sounds," from "di-" (two) and "phthongos" (sound, voice). Greek grammarians used it for a vowel pronounced as a single syllable whose sound glides from one vowel to another, as in the vowel of English "boy." The Greek term passed into Latin as "diphthongus" and then into English in the 16th century, when writers on spelling needed a name for vowel pairs like "ae" and "ou." "Diphthongate" is a later English formation, and its verb forms, including "diphthongated," follow the usual pattern for verbs built on a noun, so "diphthongated" can be used as either the past tense or a participle, and as an adjective describing a vowel that has been turned into a diphthong.
