Nothing "COSTS" x dollars, an item "COST" x dollars. Costs is plural as in there are costs involved, not this costs 10 dollars! —This comment was unsigned.
I think this is false logic here. 'costs' is used as a verb in this case. Costs is probably ungrammatical, but is widely used. 126.96.36.199 08:00, 26 July 2011 (UTC)
1974, John McPhee, The Curve of Binding Energy:
- A graphite crucible costs three dollars. Hydrofluoric acid costs seven dollars a quart, and magnesium oxide costs twenty-one dollars a pound
- costs is perfectly grammatical in the usage. It is the third-person singular present indicative of cost#Verb. DCDuring TALK 14:54, 19 March 2012 (UTC)
Possible missing sense
Three etymologies or fewer?
For English, I see three etymology sections, but none of them cites sources and I'm not convinced that they are really different. Perhaps they are just one or maybe two? --LA2 (talk) 19:50, 27 June 2012 (UTC)
