Use and Misuse / Re: When to use "have had" ?
« on: November 15, 2012, 08:17:24 PM »"Have had" is used to form the future perfect form of a verb, as in this sentence: "I will have had eaten by the time she arrives."
Erm this is not a great example. The 'had' in your sentence is unnecessary. You would actually say "I will have eaten by the time she arrives."
