condog, v. — Green’s Dictionary of Slang

condog v.

[condog is the source of a long-lived lexicographical ‘chestnut’. While assembling his dict., the lexicographer Adam Littleton (1627–94) gave the Latin word concurro (to meet, to assemble) to his assistant. The assistant, assuming, from the similarity of sounds, that the English followed the Latin, asked Littleton: ‘Concur, I suppose, Sir.’ Littleton replied tetchily, ‘Concur! condog!’ Fearing to argue, the assistant listed ‘condog’ in the manuscript as one of the meanings of concurro. It duly appeared, if only in the first edn. Unfortunately the story is marred by chronology (see cites)]

to concur, to agree.
