Society for Pure English, Tract 2, on English Homophones

Excerpt

When two or more words different in origin and signification are pronounced alike, whether they are alike or not in their spelling, they are said to be homophonous, or homophones of each other. Such words if spoken without context are of ambiguous signification. Homophone is strictly a relative term, but it is convenient to use it absolutely, and to call any word of this kind a homophone.¹
