When Should You Use TIL?

TIL vs. til vs. ’til vs. till vs. until
These forms can look almost identical, but they have different meanings. TIL usually means Today I Learned, while lowercase til can mean until. Oxford lists til as an informal conjunction or preposition meaning “until.”
Till also means “until,” while ’til is an informal shortened form of “until.” Cambridge notes that till and ’til are more informal than until and are generally avoided in formal writing.
| Form | Meaning | Example |
| TIL 💡 | Today I Learned | “TIL whales can live for decades.” |
| til | Until | “Wait til I get home.” |
| ’til | Until | “I’ll stay ’til noon.” |
| till | Until | “Wait till tomorrow.” |
| until | Up to a time | “Wait until tomorrow.” |
Does TIL Have Other Meanings?
Today I Learned is the main meaning people usually intend when they use TIL in online conversations. However, abbreviations can have different meanings in different communities or contexts.
Some sources list other possible expansions for TIL, but these are much less relevant to everyday texting and social media. Therefore, you should always check the surrounding words before deciding what an abbreviation means. If someone writes “TIL” before an interesting fact, the intended meaning is almost certainly Today I Learned.
Is TIL Slang or an Abbreviation?
TIL is best understood as an internet abbreviation used in informal communication. People sometimes call it internet slang because it appears frequently in casual online conversations, but its main function is to shorten “Today I Learned.”
It belongs to the wider group of texting and social media abbreviations. Similar examples include BTW (“by the way”), FYI (“for your information”), and IIRC (“if I remember correctly”). These shortcuts help people communicate quickly without writing every phrase in full.
TIL vs. ’til: Why Are They Different?
The difference comes down to meaning, capitalization, and punctuation. TIL means Today I Learned, while ’til means until. The apostrophe in ’til signals that the word is a shortened form.
For example, “TIL dogs can understand many human words” introduces something the writer learned. On the other hand, “I’ll wait ’til you arrive” uses ’til to mean until. Context makes the difference clear. Oxford also describes til as informal and says it appears less often in writing than until.
Can TIL Be Used in Formal Writing?
TIL mainly belongs to casual online writing. You can use it naturally in social media posts, chats, comments, forums, and friendly messages. It can sound out of place in a formal essay, business report, academic paper, or official document.
For formal writing, write the complete idea instead. Instead of “TIL that…”, you could write “I recently learned that…” or simply introduce the information directly. This keeps the tone professional and avoids unnecessary internet shorthand.
