Here is a sentence from a novel which I can't understand exactly:
"I faced forward and templed my fingers in front of my mouth, trying to give the impression that I wasn't talking to anyone at all."
I don't know what temple means here. Dictionary.reference.com only gives definitions for it as a noun, not as a verb.
I think this character covered his mouth with his fingers so hide the movement of his mouth. But what does temple mean as a verb?
