This dictionary gives a unique and invaluable description of today's Welsh, illustrated by examples drawn from a wide range of contemporary sources. It will be of interest and help to native Welsh speakers and to English speakers studying or working in Welsh.
Typically I do not bother with pocket dictionaries, much less a bilingual one, preferring to scribble stuff down until I can check something more authoritative. But this dictionary - while not perfect by any means - is pretty damn handy, as the example sentences trend colloquial and the vocabulary is typically high frequency. For what it is, very good, especially if you have a digital OCR version so you can CTRL + F.
