ILY

What does ILY mean?

Three words that people agonize over shrink to three letters here. ILY means "I love you," and every reference agrees on that: Dictionary.com, Wiktionary, and the parent guides from Verizon and Greenlight. Dictionary.com adds the detail that matters most, which is that it can be used as an earnest or a playful declaration of affection. The relationship decides which.

• Sincere. From a partner, a parent or a grandparent, ily is the full sentence, just typed quickly. "night, ily" at the end of a call is love, not a joke.
• Grateful or playful. Between friends, ily often answers a small favor. "you saved me a seat? ily" means "thank you, you're great."
• Bigger versions. ILYSM, "I love you so much," turns it up. Greenlight lists it alongside ILY.

The usual answer is "ily too" or "love you more," which returns the sentiment without making it a bigger moment than the sender intended.

Other meanings. Wiktionary notes that in American Sign Language the same handshape also works as a classifier for an airplane, so a signer moving it through the air is showing a plane, not sending love. The more familiar ILY hand sign is covered below.

Examples

• Mom to college student: "landed safe? ily, call tomorrow"
• Best friend after a ride home: "omg thank you ily"
• Couple, end of the night: "goodnight ily"
• Birthday comment on Instagram: "happy birthday to my favorite human ilysm"
• Group chat after someone shares food: "whoever brought the cookies ily"
• Grandparent learning texting: "Got the photos. Beautiful. ILY."
• Teen to sibling, sarcastic: "you ate my leftovers. ily but I'm mad"

The examples span real love, thanks and teasing, and the words around ily carry the tone. Notice that it usually closes a message, the way "love, Mom" closes a letter.

ILY, 143 and the 🤟 hand sign

ILY sits in a long line of shortcuts for the same three words.

• The ILY sign. In American Sign Language, a raised thumb, index finger and pinky combine the manual letters I, L and Y into one handshape meaning "I love you." Wikipedia's article on the sign says it was reportedly created by Deaf schoolchildren and cites the book Deaf Heritage for a 1905 origin. Dictionary.com's ILY entry links the abbreviation to this sign.
• The emoji. Emojipedia says the 🤟 Love-You Gesture emoji was approved in Unicode 10.0 in 2017 and represents the ASL sign. People drop it into texts as a visual ily.
• 143. Dictionary.com lists 143 as a related term. It counts the letters in each word: one for "I," four for "love," three for "you." It was a pager code before phones had keyboards, and it appeared in an episode of Mister Rogers' Neighborhood.

Where did ILY come from?

• 1905: The date Deaf Heritage gives for the ASL "I love you" handshape, per Wikipedia. The sign predates the text abbreviation by about a century.
• Pager era: Number codes like 143 carried the message before texting had letters to spare.
• Early 2000s: As instant messaging and texting grew, ILY became standard shorthand. An Urban Dictionary definition dates to February 2004. Dictionary.com gives the origin simply as digital communication.
• 2017: The 🤟 emoji arrives in Unicode 10.0, giving the sign a place on every phone keyboard.
• 2024 to 2026: ILY appears in nearly every parent guide to texting, including Greenlight's (updated October 2024) and Verizon's (January 2026).

Is ILY rude?

No. Nothing in it is crude, and it is fine at school. The only caution is emotional, not linguistic. An ily that arrives very early from someone a teen has only met online, together with constant gifts and attention, can be a sign of pressure; see love bombing. From friends and family, it is about as wholesome as texting gets.

How to reply to ILY

• A friend sends "ily" after you lend them a charger: "ily more, give it back by Friday though"
• Your dad texts "ILY, drive safe": "love you too, text you when I'm there"
• A coworker sends "ily" after you cover a shift: "Happy to help. You've got the next one."

If someone says ily and you do not feel the same, you do not have to say it back. A warm "that means a lot" is honest and kind.

Is ILY still used in 2026?

Yes. ILY is one of the most stable abbreviations in texting, used by teens and grandparents alike. ILYSM remains common in birthday posts and comments. Nothing has replaced it, though some friends now reach for terms like pookie to express the same fondness. For the rest of the basics, see the texting abbreviations guide or the guide for grandparents.
