Where does IG come from?

The verb guess, for “estimate” or “suppose,” dates back to Middle English.  I guess emerges at least by the late 1600s to express moderate or ironic certainty (e.g., I guess I’ll just look it up in the dictionary … or The English language, I guess, is just going do whatever it feels like).

The eye-rolling, passive-aggressive-y version of I guess is heightened in texting and online in the 1990s–2000s. If a friend asked you if you were attending a party that you weren’t super excited about, you could text back IG, showing reluctance or skepticism.

The massively popular social-media photography and video platform Instagram debuted in 2010, purchased by Facebook in 2012. Since then, some users refer to it as IG for short, just as they may use FB for its parent company. After all, with everyone being so busy on social media, who has time to type out whole words anymore?

Who uses IG?

In its I guess form, the tone of IG can express a lack of confidence or doubt or actual sincerity or irony.

The Instagram IG is seen online as a handy acronym for the app, particularly on social-media platforms that aren’t … IG.
