Dictionary Definitions while writing

This is probably a feature request, I don’t think it exists, but I could be wrong.

When I’m writing a document (for me its mostly creative writing) I find it very useful to have dictionary definitions & spellings at hand.
Previously I was using Google Docs but I want to get away from Google & LO is better in most respects.

A convenience that I painfully miss is to be able to right-click “define” on a word to check the context is appropriate.
I don’t mind using an online dictionary or thesaurus, when I really need to dig into finding the perfect word - but for common use just having an at-hand reference to a word is so useful when writing.

It would be great if there was a sidebar tab that had the definition of the currently selected word, or if that tab could be shown when right-clicking “define”

Any thoughts on this?
