As a non-native speaker, one fascinating phenomenon for me is the flip side to Uncleftish Beholding[1]. Many latinate words are considered more sophisticated, or fancier in general, than germanic words. Because I'm a native speaker of a Romance language, those are precisely the words that I reach for naturally, because they're familiar. What follows is that, past a certain threshold where your English is good enough,…
I (native English speaker) have noticed this a lot. The example that I remember most vividly is receiving advice while trying to cook food on a barbecue: A Portuguese speaking friend suggested that I "move the burgers to the periphery of the barbecue". It make perfect sense but sounded incredibly fancy to me. A native English speaker would never have said that... unless they had received a really expensive education.
English has its barbarian roots overlaid with French words from the Norman conquest of England. The French aristocracy moved in and took over. The modern result of that is the "English" words of French origin are tells of upper class origins. Americans use that, consciously or unconsciously. Sometimes it's referred to as "coded speech".
For example, someone from upper class America will "purchase" something while a lower class person will "buy" it.
It's not just slight accent changes that distinguish class in America.
