<74457.3253@COMPUSERVE.COM> Re 'plentyn mawr', in addition to the information you have already received, consider the following equivalent of 'She is a fairly big child'. In North Wales we would say, 'Mae hi'n blentyn weddol fawr'.The placing of the feminine pronoun clarifies the gender and the adverb has caused a mutation of the adjective to a 'feminine' form. Similarly, a fairly big boy would be described as, 'Mae o'n blentyn weddol fawr'. In practice though, I would say, 'Mae hi'n hogan fawr', or, 'Mae o'n hogyn mawr'. Joh Williams, Saudi Arabia.
