Thinking Welsh focuses on how common English words, phrases and constructions map onto Welsh, and highlights the key areas of difference and difficulty in these mapping operations. 150 English words and grammatical and communicative concepts are listed alphabetically, explained in clear and accessible language, and given ample exemplification to illustrate their meaning and use.All instances of mutation are marked with the usual typographic signs, and cross-references are given throughout to related entries.A list of essential grammatical terms and a Welsh index round off the manual. Thinking Welsh is a ground-breaking resource for post-beginner students wishing to explore lexical issues and master key syntactic structures as a way of attaining fluency of expression and comprehension in modern spoken and standard Welsh.
