Proto-Celtic

Suffix

*-yā f

1. Forms verbal nouns from verb stems.

   ‎*weg- (“to weave”) + ‎*-yā → ‎*wegyā (“weaving”)

   ‎*slad- (“to strike”) + ‎*-yā → ‎*sladyā (“strike”)

Usage notes

• This suffix is not the same as *-iyā (adjective nominalizer suffix), as is apparent from their different phonetic reflexes in Brittonic. In Brittonic, *-yā leaves no phonetic trace, but *-iyā results in Welsh -edd among others.
• The vocalism of the root is usually the same vocalism as the present stem of the corresponding verb.
