   Synonym: dau ddeg

Usage notes

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.

Noun
