TIL as an Abbreviation

TIL or til is an abbreviation that is usually written but isn't spoken out loud often. It is written without periods and is typically used informally in online conversations or social media posts.

History of TIL

The abbreviation TIL can be traced back to Reddit. This was originally created so that Reddit members could learn interesting or little-known facts about a topic. On December 28, 2008, a Reddit user named nix0n created a subreddit called Today I Learned. According to Google Trends, TIL has been used online since at least 2004, and its use steadily increased throughout the 2010s.

Till, 'Til and Until

Additionally, till is a synonym of until, not an abbreviation for it.

On the other hand, ‘til is an abbreviated version of until that is used from time to time, but till is generally regarded as more correct.
