twentithe

• twenteþe, twentieth, twentiþe, twentyeþe, twentythe, twentyþe
• tuentiþe, tuuentiþe (Southern, West Midland)
• twenteuþe, twentuðe (Early Middle English, West Midland)
• twentide (Northern) tuentyth, twenteat, twentyd, twentyt (Early Scots)

Inherited from Old English twēntigoþa; equivalent to twenty (“twenty”) +‎ -the (ordinal suffix).

The West Midland forms twenteuþe, twentuðe likely reflect late Old English *twēntēoþa, an alteration of twēntigoþa influenced by the ordinals for 11-19 in -tēoþa such as fīftēoþa (“fifteenth”); compare the reverse analogy in tithe, though Logan instead derives twentuðe from Old English *twēntugoþa, a vowel-reduced form of Old English *twēnteogoþa, either reflecting back umlaut of twēntigoþa or analogy to teogoþa, alternative form of tēoþa (“tenth”).
