Consider the following sentence:
Clean up the design database to initialize costing.
I find the sentence to be confusing but I'm a native English speaker. I asked my wife about it and she responded that “costing is a present participle” and “it's being nominalized (made into a noun), but we're not used to that”.
The author responded with:
"Now costing in pure grammatical sense in this case would be a noun formed from a verb. Something which american english term as verbal noun. (or like your wife mentioned is similar to a present participle). So probably grammatically this is correct"
Which is correct?
