Usage Discussion of RUN

The past tense run still survives in speech in southern England and in the speech especially of older people in some parts of the United States It was formerly used in literature, and was a standard variant in our dictionaries from 1828 until 1934. Grammarians have generally opposed it, and many people consider it nonstandard. Just about everybody uses ran in writing now.
