An English-Cornish-Welsh dictionary in two volumes (vol. i, a-peer; vol. ii, peerage-z) compiled in 1938 by T. Eurwedd Williams, by copying in two adjacent columns the English words with their Cornish equivalents given by R[obert] Morton Nance and A[rthur] S[axon] D[ennett] Smith in their English-Cornish Dictionary, produced for the Federation of Old Cornwall Societies in 1934, and adding a third column containing the Welsh equivalents. The introduction to the Nance-Smith dictionary has been translated into Welsh as an introduction to the present work.
