This book offers further insight into the complex process of second language attrition and the interacting variables that influence it. Focusing on the Irish language, it explores the language behaviour and learning experience of four Irish adults residing in Germany, who have not had contact with the Irish language in approximately 30 years. It closely examines levels of retention of lexical item knowledge and observes that seemingly forgotten information can be reactivated on re-exposure. The book is also of particular relevance for those interested in minority languages and the impact of state and education policy on language maintenance.
