(French: “Alphabetical and Analogical Dictionary of the French Language”), scholarly historical dictionary of the French language, which supplies for each entry etymology, definition, antonyms, synonyms, and cross-references.

Originally published in six volumes in Paris in 1951–64, the set was reissued with a supplement in 1970. In addition to containing all words accepted by the French Academy, it includes scientific and technical terms, commonly used colloquialisms, and archaic words that appear in classical French literature. Lengthy quotations from contemporary French writers demonstrate historical changes in the use of words and draw on modern-day examples to clarify usage. A one-volume abridgement was first produced in 1967 and revised in several successive editions thereafter.
