Seems very good,
This review is from: The Pocket Modern Welsh Dictionary: A Guide to the Living Language (Paperback)
I've just started learning Welsh, on my own, and I'm finding this dictionary very useful - not just for vocabulary, but also in helping me understand the way verbs work, tenses etc.
The only problem is, I've only had it a couple of weeks (if that), and already the crumby paperback binding is coming adrift and pages are beginning to come out. I've in no way abused the book and I'm certain every copy will be exactly the same - it's just that kind of half-hearted binding.
I'd recommend it for the content for complete beginners though - it seems to be helping me, and it's very clear. Shame Welsh seems so complicated! I will keep studying.
