A question from a reader recently showed up in my inbox. The question is “What is a hashtag?” Coincidentally the question I received arrived at about the same time as the date many people will consider the ten-year anniversary of the creation of the hashtag.
Defining what is a hashtag is much easier today than it would have been before 2014 because that is when this new word was officially added to the Oxford English Dictionary. A hashtag is a word or phrase preceded by a hash mark (#), used to identify a topic of interest and facilitate being able to search for it. English translation: A hashtag is simply a unique or almost-unique string of characters intended to make online searches more accurate.
