Coleridge's interest in philology, more specifically in English linguistics, was one manifestation—by no means the least important—of his amazing myriad-mindedness. His lectures, essays, notes, and reported conversations abound with allusions, comments, and speculations on the nature and problems of language in general and of English in particular; and his experiments in vocabulary bear additional testimony to his interest in the subject. Although increasing attention has recently been paid to this aspect of his genius, a systematic study of the subject awaits the publication of a definitive edition of his works. Nevertheless, an attempt might be made to examine certain limited phases of his interest in linguistics, particularly his theories about the nature and development of language, his observations on the character of English, and his own remarkable contributions to the enrichment of its vocabulary.
