to add more information or detail to something, such as an idea, plan, or argument, to make it clearer or more complete
Hear it in context
Notice where the phrase sounds natural.
We need to flesh out our proposal before presenting it to the board.
In my opinion, it's important to flesh out your arguments in the essay so the examiner can clearly follow your reasoning.
Fix the pattern
One small grammar move makes it sound right.
Not: Let's flesh out more the idea.
Say: Let's flesh out the idea a bit more. / flesh the idea out.
Word order: 'flesh out the idea', not 'flesh out more the idea'.
Which sounds natural?
Tap the one a native speaker would say.
'Flesh out' is the natural verb for adding detail to an outline; 'elaborate upon... with further particulars' is legalistic.
