Otto Jespersen

Born in 1860 in Denmark, Otto Jespersen became one of the most influential linguists of his era. He taught at the University of Copenhagen and built an international reputation through his work on English grammar, phonetics, and the history of language.

He is especially remembered for books such as Growth and Structure of the English Language and The Philosophy of Grammar, which brought together deep scholarship and an unusually direct, approachable style. His work often pushed against rigid rules, focusing instead on how language is actually used and how it changes over time.

Jespersen was also interested in international communication and created the constructed language Novial. He died in 1943, but his writing still matters to readers interested in English, linguistics, and the long story of how languages develop.
