The preposition "at" is used to indicate a position, location, presence, or time.
Examples:
"The plane was flying at its maximum altitude."
"The meeting was at the town hall."
"He was at the dance."
"We went to the movies at five o'clock."
*Idiomatically, there are forms at most and at least indicating an unspecific minimum or maximum. Also at work (toiling), at my request, and at it(fighting).
"There were at least ten cats on my fence last night."
"The neighborhood dogs were at it again."
"Admit to"
A preposition will use an object (noun, pronoun, or an equivalent phrase). Example: Getting dirty is part of being a cowboy. (being a cowboy is a noun phrase, object of the preposition of) Where an adverb might also be used as a preposition, look for an object: a noun or pronoun or the equivalent which normally follows the preposition. If there is none, the word in that usage is an adverb. Example: We walked on. (adverb) We walked on the beach. (preposition)
The opposite directional preposition is from.
To use "around" as an adverb, just make sure that it is not being used in a prepositional phrase. Adverb Example: I have been walking around. In the above example, "around" is not in a prepositional phrase. It is simply a word standing alone. Preposition Example: I have been walking around the house. In this example, "around" is in a prepositional phrase, so it is being used as a preposition.
No, it is not a preposition. "Away" is an adverb or an adjective.
