Etymology
Old EnglishEnglish
Seventeen comes from the Old English word 'seofontīene', which was a combination of 'seofon' (seven) and 'tīene' (ten). This structure — 'seven' + 'teen' — follows the same pattern as other English numbers from thirteen to nineteen, where 'teen' is a shortened form of 'ten'. The word has kept its basic form for over a thousand years.
