Why did “entreat” mean “to hold talks about a matter”? 

Please, can someone explain this [Oxford English Dictionary etymology](https://www.oed.com/dictionary/entreat_v?tab=etymology) in simple layman terms? I have intellectual disabilities. I have difficulty reading between the lines.

What’s the common thread running through all these senses, starting from “treat”, then “treat (a person) in a specified manner”, then “hold talks about a matter”? 

How did “treat” come to mean “treat (a person) in a specified manner”? 

Then, where do the senses of “to negotiate” and “to hold talks about a matter” come from?

>< Anglo-Norman entraiter, entreiter, entreter, Anglo-Norman and Middle French entraiter, Middle French entraictier to have a conversation with a person (13th cent. in Old French in an isolated attestation), to deal with (a matter) (late 13th cent. or earlier), in Anglo-Norman also to negotiate (a matter), to negotiate with (a person), to hold talks about a matter (all early 14th cent. or earlier), to treat (a person) in a specified manner (early 14th cent. or earlier)
