The Rudiments of English Grammar.
T. Becket et al.
Priestley (1733–1804), the scientist credited with discovering oxygen, was the greatest 18th-century intellect to give intense study to grammar. He rebelled against English grammarians’ being too heavily influenced by Latin. And he was among the earliest English-language grammarians to embrace the idea that universal usage governs propriety. He may have been the first to defend He is taller than me (treating than as a preposition) over the more orthodox He is taller than I (treating than as a conjunction).
