Although the root -position in the word preposition has nothing to do with so many prepositions' reference to positions, still try thinking about prepositions this way: you may find them easier to recognize.

Remember that the same words used as prepositions may also be used as adverbs. How does one recognize prepositions? Prepositions must always have an object that answers the question "<preposition> what?" (of what? toward what? since what?) Adverbs (apart from adverb clauses or phrases) do not have an object.
Remember, too, that the word a prepositional phrase modifies is not the same as the object of the preposition.
