Sorry, why is there a soft mutation here canwr > ganwr? Is it because of dy, or hoff, or something else?
Because of hoff (favourite). Any adjective causes soft mutation of any following noun.
Most adjectives come after the noun, a few (c10) always come before the noun, and some (c20-25), like hoff, can come before or after and create differences in meaning such as:
- unig blentyn - an only child
- plentyn unig - a lonely child
- cas beth - a most hated thing
- peth cas - a nasty thing
Is "preferred" wrong? The programme shows that the answer should be "favorite" (without an 'u'). For American Welsh learners ;)
