wythnos diwethaf

Welsh

Phrase

wythnos diwethaf

  1. last week

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]
