wythnos diwethaf
Welsh
Phrase
Usage notes
- Although wythnos is a feminine noun, the expected soft mutation of diwethaf is absent because of an old rule (now inoperative) that disallowed /ð/ after another dental consonant. Compare also nos da f (“goodnight”) with the same fossilized non-mutation.[1]
