					                   IN is a preposition. It is part of the list of prepositions. Because of that, I believe it is a preposition.
					                
					                
					             
					                   In can be a noun, a preposition, an adverb, or an adjective.
Here I believe it to be an adjective since it is describing the verb believe.
