Sweet, Henry, 1845–1912, English philologist and phonetician. An authority on Anglo-Saxon and the history of the English language, Sweet was also a pioneer in modern scientific phonetics. His History of English Sounds (1874) was a landmark in that study. In 1901 he was made a reader in phonetics at Oxford. Among his other writings are A Handbook of Phonetics (1877), A New English Grammar (2 parts, 1892–95), The History of Language (1900), The Sounds of English (1908), and works on Anglo-Saxon, Middle English, and Icelandic. Sweet was the model for Professor Higgins in G. B. Shaw's play Pygmalion.
