Have you ever seen someone write “TIL” in a text message, online comment, or social media post? If you are unsure what it means, you are not alone.
Many internet users use short forms to share information quickly.
TIL stands for “Today I Learned.” People use it when they discover a new fact or learn something they did not know before.
It is especially common on Reddit, but you may also see it on TikTok, Instagram, Facebook, and in everyday text messages.
For example, someone might write, “TIL that octopuses have three hearts.” This means the person has just learned that fact and wants to share it with others.

It does not always mean the person learned something on that exact day; sometimes, they use it simply to share a fact that is new to them.

TIL Meaning on Reddit
Reddit is one of the best-known places to see TIL. The platform has a community called r/todayilearned, where users share interesting facts they have recently discovered.
A Reddit post may begin with “TIL” and then explain the fact.
For example:
“TIL that the Eiffel Tower can become slightly taller in hot weather because metal expands when heated.”
The writer is sharing a fact they find interesting. Other users may discuss it, ask questions, or add related information.
On Reddit, TIL usually introduces a factual discovery rather than a personal update. However, users should still check whether a claim is accurate before accepting or sharing it.
TIL Meaning on Social Media
On social media, TIL is used to share interesting facts, useful tips, and surprising discoveries. Its meaning remains “Today I Learned,” although the type of content may change from platform to platform.
TIL Meaning on TikTok
On TikTok, TIL may appear in video captions, comments, or educational content.
Examples:
- “TIL why cats knead blankets.”
- “TIL how this phone setting works.”
- “TIL what this popular slang word means.”
A creator may use TIL to introduce a short educational video or an unexpected fact.
TIL Meaning on Instagram
On Instagram, people may use TIL in captions, Stories, or comments when sharing something new.
Example:
“TIL that plants can respond to changes in their environment.”
This tells followers that the person has learned an interesting fact and wants to share it.
TIL Meaning on Facebook
On Facebook, TIL can appear in posts, groups, and comments.
Example:
“TIL that my local library offers free online resources.”
Here, the person is sharing a useful discovery with friends or members of a group.
TIL Meaning on Snapchat
In Snapchat messages, TIL can introduce a fun fact or something the sender has just discovered.
Example:
“TIL that you can change this setting in Snapchat.”
The recipient can understand the abbreviation from the context, especially if the message explains a new feature or fact.
TIL Meaning in Slang and Casual Language
TIL is an internet abbreviation rather than traditional slang. Still, people often group it with online slang because it is short, informal, and common in digital conversations.
It is generally used to share information, not to insult someone or express a strong emotion.
Is TIL Always About Something Learned Today?
No. Although the full form is “Today I Learned,” people sometimes use TIL for information they discovered earlier or recently came across.
The main idea is that the fact is new to the person sharing it.
For example:
“TIL that this book was published decades ago.”
The person may have discovered this information today, even if the book itself is much older.
Can TIL Be Used as a Joke?
Yes. Someone can use TIL to share an obvious fact sarcastically or humorously.
Example:
“TIL that Monday comes after Sunday.”
This may be a joke because most people already know that information.
The tone depends on the conversation. TIL itself does not automatically make a sentence sarcastic.
TIL Meaning in Love and Relationships
TIL does not have a special romantic meaning. In relationships, it usually keeps its normal meaning: “Today I Learned.”
People may use it when they discover something new about their partner, relationship habits, or communication.
Examples in Relationships
Example 1
“TIL that your favorite movie is a comedy.”
Meaning: The sender has just learned something about the other person.
Example 2
“TIL that you prefer phone calls over texting.”
Meaning: The sender has discovered a communication preference.
Example 3
“TIL that we both like the same music.”
Meaning: The sender has found something they share.
TIL does not mean “I love you,” “thinking of you,” or any other romantic phrase by itself. If someone sends it during a romantic conversation, the surrounding words determine the message.

TIL vs. Similar Internet Abbreviations

TIL vs. FYI
TIL highlights something the sender has learned. FYI introduces information that the recipient may find useful.

- TIL: “TIL that this website has a free learning section.”
- FYI: “FYI, this website has a free learning section.”
The first emphasizes the sender’s discovery. The second simply passes along information.
TIL vs. BTW
TIL introduces a new fact or discovery. BTW adds another thought to a conversation.
Example:
- TIL: “TIL that this word has a French origin.”
- BTW: “BTW, I found another interesting word.”
These abbreviations serve different purposes.
TIL vs. TMI
TIL means “Today I Learned,” while TMI means “Too Much Information.”
For example:
“TIL that some birds can recognize human faces.”
This shares a fact.
“TMI! I didn’t need to know all those details.”
This suggests that someone has shared more information than the listener wanted.
Common Mistakes When Using TIL
