Angus Watson's Essential Gaelic-English and English-Gaelic dictionaries are well-established as one of the leading dictionaries of the Gaelic language. This combined dictionary is ideal for learners of Gaelic at all levels, and its generous coverage of vocabulary from fields such as business and IT makes it a valuable tool for all those who require an up-to-date reference work.

It contains a large amount of explanatory material, numerous examples of usage and idiomatic phrases and expressions. Many registers and styles are sampled, from the familiar (and occasionally the vulgar) to the formal and the literary. Cross-references draw the user to related words and expressions, and Scots equivalents are provided for a number of headwords.
