I noticed a sign on the back of a van today. It said, 'Pipe and cable locating'.
My first reaction was that it should have said, 'Pipe and cable location', as I think location is the noun that best describes what I presume this company does - scan for pipes before the client excavates.
But they used a gerund, a verb form that operates as a noun.
On reflection, I think the sign is clever, in that the gerund form creates a subtle advertisement for them as an active business that will do things for you.
