What does the word ess mean in German language?

The word "ess" in German is not a stand-alone word. It's actually a part of the word "es", which is the third-person singular neuter pronoun in German.

Here are some examples of how "es" is used:

* Es ist kalt. (It is cold.)

* Es regnet. (It's raining.)

* Es gibt keinen Kaffee mehr. (There is no more coffee.)

"Ess" can also be a short form of "essen", which means "to eat". However, it's not commonly used in modern German.
