red underline

Spellcheck's visual warning

A red underline is a visual indicator appearing beneath text, typically in word processors and web browsers, marking spelling errors.

The convention is now nearly universal in digital writing tools: red for misspellings, green or blue for grammar issues.

My essay was covered in red underlines.

The feature has shaped how people write, offering instant feedback that earlier generations lacked.
