A Zyngite is a WWF Easter Egg. Certain (wrong) words will bring up a popup saying you have found a Zyngite (I've had it happen with dogg and lazer)
A Zyngite is a word that you play, thinking it should be a valid word to play in the game, but isn't! Examples are: CAVA, LAZER and PIXI. If you play one of these in Words with Friends, you will get a pop-up telling you that you have found a Zyngite.
In the context of a game, a "zyngite" likely refers to a collectible item, resource, or unique creature that players can discover and collect. It may have special properties or abilities that enhance gameplay, contribute to crafting, or serve as part of a quest. The specific characteristics of a zyngite would depend on the game's mechanics and lore.
