Here are some possibilities:
* Spanish: In Spanish, "es" means "is" or "it is."
* German: "Es" means "it" in German.
* French: "Es" is not a word in French, it might be a misspelling of "est" which means "is."
* Other languages: It could be a word from another language.
* Misspelling: It could be a misspelling of another English word.
Please provide more context so I can help you figure out what "es" means.
