One thing that I recognize in people that sound more eloquent is that they pick the most accurate words when possible, having in consideration when to abstract out or when to be more specific to do not distract you, from the main point.

Sort of not generating ambiguities in the listeners head by using very specific terms. At the same time use more abstract words for the aspects that are no so relevant in the conversation. This is one observation I made, because I’d like to become more eloquent but as you can see I’m not quite there yet hahaha. Thanks for posting this interesting question.
