Simlish is the fictional language spoken by Sims characters in The Sims video game series, created by Maxis and Electronic Arts. It was designed by Will Wright to sound like a real language without being directly translatable, blending influences from English, Ukrainian, Tagalog, Romanian, and Navajo.

How accurate is this Simlish translator?

The translator uses 200+ confirmed Simlish words and phrases from across the game series. For words not in the official dictionary, it applies Simlish phonetic rules (CVC patterns, characteristic sound substitutions) to generate plausible Simlish output.

What does "Sul sul" mean in Simlish?

"Sul sul" is one of the most famous Simlish phrases — it means both "hello" and "goodbye," similar to the Italian word "ciao."

What does "Nooboo" mean?

"Nooboo" is the Simlish word for "baby." It is one of the most recognisable and commonly used Simlish words in the game.

Can I translate Simlish back to English?

Yes! Switch to "Simlish → English" mode and enter your Simlish phrase. The tool will reverse-look up all known Simlish words and return their English equivalents.

Is there an official complete Simlish dictionary?

An official Simlish dictionary exists internally at Maxis/EA and is provided to voice actors, but it has never been publicly released in full. This tool compiles all publicly confirmed translations from across the game series and fan research.
