verb / noun
bite
BYTE/baɪt/
The act of closing teeth to cut or grip something.
She bites into the apple while holding it firmly.

Etymology
Old English bitan already meant piercing or cutting with the teeth. The modern verb preserves that concrete action rather than developing from a figurative meaning.
In context
If I didn't have a stick and I went in to grab that tail, he would just bite me. Huge fangs.
