What makes you think that? I’m curious. I would’ve assumed something like Inuktitut (1 word conveys subject verb object tense …) or something like toki pona (removes unused information) or maybe a highly analytical language like one of the Chinese languages.
IIRC it takes about 30ish minutes for caffeine to “kick in”. So if you have a bit, then take a nap, it can give you a nice 20ish minute power nap, then naturally wake you up so you don’t feel groggy. The key is to be able to fall asleep quickly enough to have a decent power nap before it kicks in.
