WelshEdit

EtymologyEdit

From Old Welsh uceint, from Proto-Celtic *wikantī, from Proto-Indo-European *h₁wih₁ḱm̥t (compare Latin vīgintī) from *dwi(h₁)dḱm̥ti (two-ten). Cognate with Cornish ugens, Breton ugent, Old Irish fiche.

PronunciationEdit

Usage notesEdit

  • Despite being written as u, the initial vowel here is /ɪ/ in north Wales.

NumeralEdit

Welsh cardinal numbers
 <  19 20 21  > 
    Cardinal : ugain
    Ordinal : ugeinfed
    Decimal : dau ddeg

ugain

  1. (vigesimal) twenty
    Synonym: dau ddeg

Usage notesEdit

Numerals which employ ugain as their final element, i.e. 21 to 39, use ar (on) to connect it to the preceding element, which causes an aspirate mutation, e.g. un ar hugain (twenty-one), pedwar ar bymtheg ar hugain (thirty-nine). Elsewhere in the language, ar causes a soft rather than aspirate mutation.

NounEdit

ugain m (plural ugeiniau)

  1. twenty
  2. (numeral) score

MutationEdit

Welsh mutation
radical soft nasal h-prothesis
ugain unchanged unchanged hugain
Note: Some of these forms may be hypothetical. Not every
possible mutated form of every word actually occurs.
