Etymology: Epenthesis comes from Greek "epenthesis," literally "a putting in" or "insertion," built from "en" (in) and "thesis" (a placing), the same "thesis" that appears in words like "synthesis" and "hypothesis." Ancient Greek grammarians used it as a technical term for adding a sound to a word, and the term was carried into Latin and then into English, where it entered the vocabulary of grammar and linguistics. The plural "epentheses" is simply the Greek-derived plural ending "-es," so it describes more than one such insertion. Familiar English examples show the process at work. The "b" in "thimble," which descends from Old English "thymel," was added so the sound after the "m" was easier to say, and "empty" gained its "p" in a similar way over time. In the plural "epentheses," the "e" between "epenthesis" and "s" is inserted to make the ending pronounceable after the "s" sound, a small illustration of the very process the word names.
