gumption
n. US //ˈɡəmpʃən// UK //ɡˈʌmpʃən// gump·tion
Borrowed from Scots gumption (“common sense, shrewdness; drive, initiative”); further etymology unknown, possibly connected with Middle English gome (“attention, heed”), from Old Norse gaumr (“attention, heed”), from Proto-Germanic *gaumō. English cognates include gaum (“to comprehend, understand”) and goam (“to recognize, see”).
