What “hashtag” means
Wiktionary · Wikipediahashtag/ˈhæʃˌtæɡ/
- nounA metadata tag, signaled by a preceding hash sign (#), used to label content.
- verbTo label (a message) with a hashtag.
A hashtag is a metadata tag operator that is prefaced by the hash symbol, #. On social media, hashtags are used on microblogging and photo-sharing services–especially Twitter and Tumblr–as a form of user-generated tagging that enables cross-referencing of content by topic or theme. For example, a search within Instagram for the hashtag #flowers returns all posts that have been tagged with that term. After the initial hash symbol, a hashtag may include letters, numerals or other punctuation.
