What “underline” means
Wiktionary · Wikipediaunderline/ˈʌndəˌlaɪn/
- nounA line placed underneath a piece of text in order to provide emphasis or to indicate that it should be viewed in italics or (in electronic documents) that it acts as a hyperlink.
- verbTo draw a line underneath something, especially to add emphasis; to underscore
An underscore or underline is a line drawn under a segment of text. In proofreading, underscoring is a convention that says "set this text in italic type", traditionally used on manuscript or typescript as an instruction to the printer. Its use to add emphasis in modern finished documents is generally avoided.
