Q: I’m seeing the use of “I’ve” where “have” is not an auxiliary but the actual verb, as in “I’ve a red car.” That’s not legit, is it? Yuck.
A: We’ve searched the major scholarly works of grammar and haven’t found any grammatical objections to using “I’ve” as a contraction when “have” is the primary verb. However, the usage is more common in Britain and may sound unidiomatic to American ears.
In British or American English? A Handbook of Word and Grammar Patterns (2006), the linguist John Algeo writes that the use of “I’ve” with the contracted primary verb is over five times more frequent in the UK than in the US.
What you’re noticing, however, may be a shortening of the word “have” in speech or written dialogue, rather than an actual contraction. The “h” or “ha” sounds are often dropped in conversation, and the contraction itself is elided when an expression like “I’ve got to go” comes out as “I gotta go.”
As for the contraction, Sydney Greenbaum, writing in the Oxford English Grammar, describes “I’ve” as the contracted form of “I have” when “have” is either a primary verb or an auxiliary.
We couldn’t find any objections to the usage in The Cambridge Grammar of the English Language, by Rodney Huddleston and Geoffrey K. Pullum, or A Comprehensive Grammar of the English Language, by Randolph Quirk et al.
However, both books question the usage in some negative constructions.
Quirk, for example, says it’s generally preferable to contract “not” rather than “have” in such constructions, recommending “I haven’t” instead of “I’ve not.” Huddleston and Pullum consider sentences like “I’ve no time today” and “I haven’t enough tea” to be grammatical only in certain dialects.
We checked a half-dozen standard dictionaries and all of them define “I’ve” as simply a contraction for “I have.” None of them say it can’t be used to contract the principal verb. In fact, two of the dictionaries include examples that do just that:
“I’ve one more appointment today” (from Merriam-Webster Unabridged) and “I’ve no other appointments” (from the online Collins Dictionary).
Finally, none of the usage manuals in our extensive language library comment on the use of “I’ve” as a contraction for “I have,” suggesting that the authors aren’t especially bothered by the way “I’ve” is being used today in either in the US or the UK.
