same: [12] Same comes ultimately from Indo- European *somós ‘same’. This also produced Greek homós ‘same’ (source of the English prefix homo-, as in homosexual), and was a variant of the base that gave Latin similis ‘similar’ (source of English similar and simulate), Latin simul ‘at the same time’ (source of English assemble and simultaneous), Latin simplus ‘simple’ (source of English simple).
Latin singulus ‘single’ (source of English single and singular), and English seem and some. The Indo-European adjective passed into prehistoric Germanic as *samaz, which in due course evolved into Old Norse same. The Vikings brought the word with them to England, where it gradually replaced the native terms for ‘same’, ilk and self.
