A caret is a small mark that looks like an upside-down V: ^. Writers and editors use it to show where something should be inserted into a sentence. If you're revising an essay and realize you forgot a word, you can draw a caret below the line where the word belongs, then write the missing word above it.

The caret works like a pointing finger saying “add this here.” You might write a sentence like “The dog ran the park” and then notice you're missing a word. Draw a caret between “ran” and “the,” write “to” above it, and now your sentence reads correctly.

You'll see carets in handwritten corrections, proofreading marks, and even in computer programming, where the ^ symbol has special technical meanings.

Teachers often use carets when grading papers to show students where to add words, punctuation, or details. It's one of the most useful proofreading symbols because it keeps corrections neat and clear without crossing out or rewriting entire sentences.
