My friend and I are debating whether or not "costed" should be used in a particular sentence.
"I wonder how much it costed to get all of that paint on."
I understand "costed" to be used when something like "priced" or "valued" would work, like
"He costed the vacation to be somewhere around three thousand dollars"
meaning he calculated the cost of the trip. I don't think that using "costed" in the first sentence serves that purpose. In response to these thoughts, my friend said this:
"'Costed' is inflected for the dummy pronoun 'it' which is coreferential with the infinitive phrase 'to get all of that text painted on.' 'To cost' is a transitive verb where the agent is the thing being purchased, which is 'it'. Have you only ever used 'to cost' as a where the thing being purchased is a patient?"
As you may be able to tell, my friend is a bit more linguistically inclined than I am, and I don't really understand what this whole thing means. Can someone translate, and tell me if he's right?
