+### Spell checker
+
+The `flyspell` package is a built-in Emacs minor mode that provides on-the-fly spell checking. It highlights misspelled words as you type, offering interactive corrections. In text modes, it checks the entire buffer, while in programming modes, it typically checks only comments and strings. It integrates with external spell checkers like `aspell`, `hunspell`, or `ispell` to provide suggestions and corrections.
