does any language nerd cutie know what's the official theory on why capital letters are a thing?
they just seem really pointless to me because:i know where the sentence begins, because there is either nothing before it or there is a period letting me know the previous sentence is over
they don't signal emphasis in grammatically correct language
names? who the fuck cares what size letter they begin with i will know from context thank you
