Patrick Stephen Dinneen, Foclóir Gaeḋilge agus Béarla (1904)
“ In writing the language, words only recently borrowed and for which there are Irish equivalents, should be sparingly used. It is otherwise with words that have already a life of a couple of hundred years in the language. Every tongue borrows from other tongues, and it is a sign of health and vigour when a language can assimilate a crop of foreign words and reduce them to subjection by the rigorous application of its own syntax and of its own inflexional forms. ”
