# meaning # hashtag meaning – 2017

The symbol # is most commonly known as a number sign, hash,[1] or pound sign.[2] Other names include octothorpe and hashtag. The symbol is used for a variety of purposes, including the designation of a number (for example, “#1” represents “number one”), an abbreviation for pounds avoirdupois, a metadata tag on social media platforms,[3] and a button on touch-tone telephones. The symbol is defined in Unicode and ASCII as U+0023 # NUMBER SIGN (HTML #).

The musical symbol called sharp (♯) is different and has a different Unicode assignment. A sharp cannot have horizontal lines (to avoid being obscured by the horizontal musical staff lines), while in most fonts the number sign has horizontal lines.

Twitter documentation refers to it as “the hashtag symbol”[25] The word “hashtag” is often used when reading social media messages aloud. For instance the text “#xyz” is often read out loud as “hashtag, x, y, z” (as opposed to “hash, x, y, z” or “number sign, x, y, z”).




hashtag – a word or phrase preceded by a hash sign (#), used on social media sites such as Twitter to identify messages on a specific topic.

A hashtag is a type of label or metadata tag used on social network and microblogging services which makes it easier for users to find messages with a specific theme or content. Users create and use hashtags by placing the hash character (or pound sign) # (also known as number sign or octothorpe) in front of a word or unspaced phrase, either in the main text of a message or at the end. Searching for that hashtag will then present each message that has been tagged with it. A hashtag archive is consequently collected into a single stream under the same hashtag
