No language course has ever, can, or ever will be comprehensive enough to cover EVERY aspect of learning a "tongue" that is not one's primary form of communication. Even the most encompassing language acquisition programs need supplemental materials. McGonagle's "Irish Grammar: A Basic Handbook" is one such essential supplement that is easily used in tandem with any and every Irish Gaelic Program available today. McGonagle cuts to the chase, guts out all the superfluous grammar gooble-de-goop, and serves up a grounding in grammar necessary to grasping the Irish Gaelic Language. The fundamentals are dished up in "bite size" portions, and is an easy to use reference guide for beginner and "brush-up" students alike. The only negative observation that needs to be mentioned about the "Handbook" is that it does not come with an Audio CD so a novice can hear the examples of various points and vocabulary, perferably spoken by "Native Speakers." Maybe future editions could include an audio CD or two.
