Word History

chain-blend (or "longest word" accretion) coined by Professor Sendy, formed by overlapping the terminal phonemes of one word with the initial phonemes of the next so that each component shares a seam with its neighbor. The constituent links, in sequence, are DEFENESTRATE → (defenestra)tion + (ban)SHEE → NOMINAL → SEMINAL → (semina)LUNAR → KIRKOLA → (kirko)la + (a)BURGER → BENTAL → INSTRUMENTAL → MINIMAL → (minima)LAURA / AURA, each junction elided into the following stem. The newest installment grafted onto the front of the running word is the defenestrate–banshee segment ("defenestrachee"). Built on the model of Sendy's other ever-lengthening composite headwords.
