In both British and American English it is standard before a word (as more or less) indicating degree "a couple more examples of Middle Englis h writing --Charles Barber". Its use before an ordinary plural noun is an Americanism, common in speech and in writing that is not meant to be formal or elevated "the first couple chapters are pretty good --E. B. White (letter)" "still operated a couple wagons for hire --Garrison Keillor". It is most frequently used with periods of time "a couple weeks" and numbers "a couple hundred" "a couple dozen".
