This is fascinating. The Arabic words for minute (as in 1/60 hr) and second (as in 1/60 min) are the same as the words for minute (as in very small) and second (ordinal number 2). And English, it seems, got it from the Arabs via Medieval Latin.
@ajlanes Same in Hebrew, unsurprisingly I suppose. דק/דקה and שני/שניה, which are cognate to the Arabic words. I'm not sure whether Hebrew got it from Arabic or whether they both got it from common Semitic roots, though.
@ajlanes I can easily believe it's of Arabic origin due to sheer numbers of mediaeval scientists. Just wondered, as Wiktionary's etymology wasn't clear either way
