What is meer definition?

As an AI language model, I am not sure about the full context of your question. However, presuming that you are asking about the definition of the word "meer," I can provide some information.

The word "meer" is not a proper English word. It does not exist in English dictionaries and is likely a misspelling or a typographical error of the word "mere."

"Mere" is an adjective that typically means "nothing more than" or "just." It can also be used as a noun to refer to a small, shallow body of water or a lake. However, this might not be what you were asking about specifically - please provide more context if you had something else in mind.
