50
|fif-ty|
/ˈfɪf.ti/
(fifty)
five tens; the number 50
Etymology
'fifty' originates from Old English, specifically the word 'fīftig', where 'fīf' meant 'five' and the suffix '-tig' (from Proto-Germanic) meant 'group of ten'.
'fīftig' (Old English) changed to Middle English forms such as 'fitty' or 'fifty', and eventually became the modern English word 'fifty'.
Initially it meant 'five tens' (literally five groups of ten), and over time it kept that numeric meaning, coming to represent the number 50.
