Bight and bite are homophones and easily confused words. Many people expect their software or an app to catch all spelling and grammar mistakes for them, but neither is a perfect system. Spell-check wouldn’t necessarily catch a slip-up of bight and bite, for example, because they are both words and they are spelled correctly. Spell-check really doesn’t consider context. Auto-correct suffers from a similar problem.
Bight is a noun. It’s a geography term for a bend or curve of land on a coastline, a body of water within a bend of land that’s shallower than a sound or a harbor.
Bight is also the curvature of string or rope, as opposed to its frayed ends.
Bite is a noun, meaning a portion of food a person can remove from their fork or a chunk of food using their mouth.
Bite can also be a verb, meaning to remove a portion of a chunk of food (i.e., cake, cookie, pizza slice), It can also mean to injure a creature or an object with one’s teeth.
The following story uses both words correctly:
When Bridge was small, he loved to look at maps and the shapes of land masses. He admired how some coastline bights looked like a hungry giant had come along and taken a bite out of them.
