The correct spelling of the word "study atimpassive" is actually "stoic and impassive." It is often misspelled due to the similarity in sound between the two words "stoic" and "study." "Stoic" is pronounced /ˈstoʊɪk/ while "study" is pronounced /ˈstʌdi/. Additionally, "impassive" is often spelled with a single "s," but the correct spelling is with two "s's": /ɪmˈpæs.ɪv/. The phrase "stoic and impassive" describes someone who shows no emotional reaction to something, regardless of how intense or emotional it may be.
