Alex, quit - quit - quit, or quitted. "Quitted" is an older form of the past participle of the verb "to quit". It has fallen out of use in British English but is still used in American English, though rarely, mostly by writers who wish to impress you with their knowldege of obscure words, and by foreign students. The Encyclopedia Brittanica (1843 edition) used the word 19 times. -His father, being reduced to a state of poverty, quitted his native country and settled at Alderton. -He was after admitted to Cambridge College, which he quitted immediately, and never returned. Considering the fact that English is now international in scope, perhaps the word will become popular again due to its use by speakers of English as a second language. It is possible, at least in theory, for non-native speakers to influence the future development of the English language. What do you think?
