Idioms are key to speaking a language in a natural manner. This collection of nearly 2000 Gaelic idioms was made at a time prior to many English expressions coming into the language. This new edition contains not just MacDonald`s original work but is supplemented with a collection made in the 20th century and published in An Deò-gréine, the newsletter of An Comunn Gàidhealach. As well it contains a collection of idioms made more recently from Gaelic speakers from Nova Scotia.
