I have been reading about inversion structures in Welsh. In verb phrase inversions the prepositional aspect markers usually invert with the verb phrase. The exception is `yn' which is absent from the inverted clause. Mae John yn palu'r ardd. John is digging in the garden. Palu'r ardd mae John. Digging in the garden is John. I have read that this is an idiosyncratic fact about `yn' and that the mutation caused by `yn' remains on the fronted VP. Since my dictionary lists palu `dig' it seems there is no affect of mutation in the above example. Could anyone tell me why this is? I thought (Lesson 4!) that `yn' caused soft mutation, p --> b... Also could anyone provide me with an example where the mutation caused by `yn' can be seen in the fronted VP? Thanks and Pob hwyl, Robin Schafer
