Unlike dictionaries, this book, like its Welsh counterpart, provides the more commonly used Manx words to use for everyday situations. Also, it does more than provide a translation for each word; it also gives an example sentence for each word or expression so that you can see the words in context. In addition, there is also a brief grammar section to explain pronouns, prepositions and prepositional pronouns, irregular verbs, etc.
The book can be bought easily online here. It costs 10 pounds plus shipping. I highly recommend this book for anyone learning Manx.
