One of the the best ways to learn to speak Gaelic, or any language, is by first listening and then repeating and speaking, much like how children learn language. However, since everyone has their own style of learning, it depends on the learner and the situation. Knowing Gaelic will allow someone to communicate with Irish speakers.
Gaelic, also known as Irish, is primarily spoken in Ireland. Speakers mainly live in the Gaeltachtaí region on the west coast of the country, where approximately 76 percent of the population speak Gaelic. The language is part of the Goidelic branch of the Celtic language family, and has similarities to Scottish Gaelic and Manx. There are three major dialects: Connacht, or Connachta; Ulster, or Ulaidh; and Munster, or An Mhumhain.
