Other forms: oinking; oinks; oinked
An oink is the sound a pig makes. If you're on the hunt for your neighbor's run-away piglets, be sure to listen carefully for oinks.
In Japanese, pigs "buu," in German they "grunz," and in Swedish they "nöff." In English, however, we describe the sound pigs make as an oink and we say that when they make this noise, they oink. All of these words are imitative, each language's best imitation of the grunting-squeaking-squeal that's unique to our porcine pals.
