The Welsh Academy English–Welsh Dictionary (Welsh: Geiriadur yr Academi; sometimes colloquially Geiriadur Bruce, 'Bruce's Dictionary'[1]) is the most comprehensive English–Welshdictionary ever published. It is the product of many years' work by the editors Bruce Griffiths and Dafydd Glyn Jones. The dictionary was published in 1995, with a second edition published in September 2003.
