What is the proper name for the pointed prongs on a fork? Answer
The proper name for the pointed prongs on a fork is a tine.
While most dinner forks have four tines, serving forks or dessert forks might have three, and some specialty forks have only two. The word “tine” is not exclusively for forks; it can also refer to the prongs on a pitchfork, the teeth of a comb, or even the antlers of a deer.
