In spoken and written language, stretched words can modify the meaning of a word. For instance, "suuuuure" can imply sarcasm, while "yeeessss" may indicate excitement. Stretched words are rare in formal writing, but the rise of social media has opened up new opportunities to study them.

Gray and colleagues have now completed the most comprehensive study to date of "stretchable" words in social media. They developed a new, more thorough strategy for identifying stretched words in tweets and used it to analyze a randomly selected dataset of about 10 percent of all tweets generated between September 2008 and December 2016 -- totaling about 100 billion tweets.
