alt Hacker NewsI agree that utilize is distinct from use, in that it makes something useful in a novel way; you might utilize a flat stone to dig, where you would otherwise use a shovel.
But I also agree with GP that many words like this are chosen just to sound more impressive, in the same way that people say 'at this time' instead of 'now.'
This helped me understand what I was getting at so I’ll try explaining again now with that.
The words are typically used in two different contexts, one more professional (utilize) and one more casual (use). The words can be chosen to hint at which context we’re in or shift the context locally if needed.
For example, a story about a group of drunk guys could say that one of them utilized a flat stone to dig, to add humour since we’re clearly not in that professional context.
