Simlish Translator
This Simlish translator converts English into Simlish, the invented sims language used across every game in The Sims series. Use it as a simlish to english translator too, for decoding sul sul, dag dag, and the simlish phrases you've heard in the games. Free, no signup.
What Is Simlish?
Simlish is the fictional sims language created by Maxis and used in every game in The Sims series since 1996. This simlish translator converts English into Simlish and works the other way too, from simlish translation back into English.
Simlish wasn't designed to mean nothing. It was built to feel emotionally readable without locking the game to any real language, so players pick up meaning from tone and delivery without needing a simlish dictionary to follow along.
Use this tool to look up simlish words, decode phrases from the games, or generate Simlish text for creative projects. For other fictional languages, the Elvish Translator covers Tolkien's constructed elvish from Middle-earth.
How to Use This Simlish Translator
Sul sul! Here is how the Simlish translator works:
- Type or paste English text into the left box
- Hit Translate to get the Simlish result
- Copy the output, or swap to change direction
To decode, type Simlish into the left box and click Swap before translating. The simlish to english translator direction works just as well, so translating simlish to english takes the same steps.

When Would You Actually Use This?
Most people arrive here for one of these reasons:
- Sims 4 gameplay: Players use simlish phrases during builds, machinima, and sims 4 language content to make in-game videos feel authentic.
- Creative projects and simlish font overlays: Designers and cosplayers drop simlish words into captions, graphics, and text overlays to style content around The Sims aesthetic.
- Simlish curse words: Yes, they exist, and fans want to know exactly what their Sims are saying when things go wrong.
- Learning how to speak simlish: Some fans want to learn simlish well enough to improvise it convincingly in TikTok videos or YouTube Let's Plays.
My cousin spent an afternoon learning simlish just so she could subtitle her Sims Let's Play in the actual sims language. She ran phrases through this translator to make sure her sul sul and dag dag sounded right before she recorded.
For another fictional constructed language with real depth, the Klingon Translator covers the language Paramount built for Star Trek.
What Makes This Simlish Translator Work
Most simlish resources online are static word lists with no translation functionality, and some generators produce random gibberish that doesn't match any documented simlish language vocabulary. That's a problem when you need accurate simlish phrases for a video or a creative project.
This tool uses AI trained on documented simspeak vocabulary and simlish alphabet phonology compiled from Maxis production notes, fan-documented phrase lists, and recordings from across the Sims series. It handles both directions: english to simlish and simlish translation back to English.
For more fictional language tools, the Elvish Translator covers Tolkien's elvish and the Klingon Translator covers Star Trek's most complete constructed language. The Wikipedia article on Simlish covers its creation, the real musicians who recorded Simlish versions of their songs, and why Will Wright designed it to be untranslatable.
