IPA: /ˈtæɡ.laɪn/
KK: /ˈtæɡlaɪn/
A short and catchy phrase used in advertising or branding to represent a product, company, or idea.
The company's tagline is memorable and perfectly captures its mission.
Tagline → The word is formed from "tag" (from Old Norse *taggr*, meaning a string or a label) and "line" (from Old English *līn*, meaning a line or string). A tagline is essentially a line or phrase that labels or summarizes something, often used in advertising.
Think of a 'label' ('tag') that summarizes a message in a 'line' — that's what a tagline does.
