I have mixed feelings about this dictionary. It is edited by Gareth King, the author of my favourite Welsh grammar book. On the positive side, the layout is extremely clear, the translations seem to be accurate and there are plenty of examples given to help choose the right word and apply it correctly, including good coverage of idioms. However, it seems to have a fairly limited range of vocabulary and is missing even some fairly common words. I find my Welsh children's dictionary (Geiriadur Gomer i'r Ifanc) to be much more comprehensive. This book is, however, great for the words that it covers and would make an excellent choice as a learner's dictionary. It is still my main two-way bilingual Welsh-English dictionary. ( )
