(linguistics, countable) a mutation
- 1996, Peter Wynn Thomas, Gramadeg y Gymraeg, Gwasg Prifysgol Cymru, page 683:
  Er mor sylfaenol yw treiglo i ramadeg y Gymraeg, dim ond ar naw cytsain y gall effeithio. Y mae'r newidiadau'n ymddosbarthu'n dair prif gyfres o dreigladau, sef: i. y treiglad meddal, ii. y treiglad trwynol, a iii. y treiglad llaes.
  Despite mutation being so fundamental to Welsh grammar, it can only affect nine consonants. The changes are classified into three main series o mutations, namely: i. the soft mutation, ii. the nasal mutation and iii. the aspirate mutation.
(obsolete) inflection
Synonym: ffurfdroad
