Wherever it has been necessary I have transcribed words phonetically according to the system of the Association Phonétique Internationale, though without going into too minute distinction of sounds, the object being, not to teach the exact pronunciation of various languages, but rather to bring out clearly the insufficiency of the ordinary spelling. The latter is given throughout in italics, while phonetic symbols have been inserted in brackets [ ]. I must ask the reader to forgive inconsistency in such matters as Greek accents, Old English marks of vowel-length, etc., which I have often omitted as of no importance for the purpose of this volume.

I must express here my gratitude to the directors of the Carlsbergfond for kind support of my work. I want to thank also Professor G. C. Moore Smith, of the University of Sheffield: not only has he sent me the manuscript of a translation of most of my Nutidssprog, which he had undertaken of his own accord and which served as the basis of Book II, but he has kindly gone through the whole of this volume, improving and correcting my English style in many passages. His friendship and the untiring interest he has always taken in my work have been extremely valuable to me for a great many years.
