Seo eagráin nua, in aon imleabhar amháin, de "Slí an Eolais" agus "Eagna an Ghaeil", leis an Ollamh Cormac Ó Cadhlaigh. Cnuasach téarmaí, seanfhocal, nathanna cainte, agus blúirí litríochta is seanchais, agus iad rangaithe de réir téama (mar shampla, baill bheatha an duine, sláinte, am agus aimsir, clann agus muintir) atá in "Slí an Eolais". Leabhar coimhdeach ag "Slí an Eolais" é "Eagna an Ghaeil", a bhfuil míniú ann ar sciar mór de na seanfhocail atá in "Slí an Eolais" maille le míniú ar neart nathanna cainte eile agus sleachta machnaimh ar ghnéithe éagsúla den saol. Tá lear eolais agus saibhreas teanga sa dá shaothar seo, roinnt mhaith de ligthe i ndearmad, b'fhéidir, agus an té a shúfaidh chuige a bhfuil iontu, saibhreofar go mór a chur amach ar Éirinn agus ar a teanga. Tá léargas suimiúil iontu, leis, ar an saol in Éirinn sna 1920idí (an tráth a foilsíodh an dá leabhar) agus ar na tréithe a bhain leis-an mórtas cine, an chráifeacht, agus ciall do stair agus do dhúchas na hÉireann. -- This is a new edition, in a single volume, of "Slí an Eolais" and "Eagna an Ghaeil", by Professor Cormac Ó Cadhlaigh. "Slí an Eolais" ('The Way of Knowledge') is a collection of terms, proverbs, expressions, literary fragments and folklore, all thematically classified (for example, the human body, health, time and weather, children and family). "Eagna an Ghaeil" ('The Wisdom of the Gael') is a companion to "Slí an Eolais", which explains of the majority of the proverbs in "Slí an Eolais" as well as elucidating many expressions and observations on various aspects of life. These two books contain such an abundance of information and such richness of language, much of it forgotten, perhaps, that readers who absorb the contents of the two will will find their knowledge of Ireland and the Irish language greatly augmented. The books also provide a fascinating insight into the Ireland of the 1920s (when both books were published) and its distinctive characteristics-national pride, piety, and an awareness of Ireland's history and heritage.
