in heraldry, having a head emerging from or set within the mouth (gule or gorge) of another animal's head.
From heraldic terminology: en- (in) plus goule/gule (from Old French, meaning throat or mouth). This specialized term applies to the visual convention in coats of arms where one animal's head appears inside the open mouth of another.
Heraldry is full of wonderfully specific vocabulary, and 'engouled' is a perfect example—medieval heralds needed precise terms to describe visual arrangements in coats of arms, and this one beautifully captures the slightly grotesque image of one creature's head emerging from another's mouth.
