The name of Otto Jespersen is a household word to all advanced students of English. Who has not again and again consulted the volumes of the Modern English Grammar, this inexhaustible mine of systematized knowledge, and found there just the information he wanted? Many teachers and scholars have received valuable impulses from the Growth and Structure of the English Language, Essentials of English Grammar, Philosophy of Grammar, and Language, the acme of Jespersen's scientific efforts. Many other books and papers may be mentioned in which he has shed new light on or definitely solved some linguistic problem, or in which he simply is the model teacher. So it seems natural that the Englische Studien, to which, by the way, he has contributed papers from the eighties on, should bring a mention of Otto Jespersen and his work.(1)
