Question

What is the difference between adverb and preposition? ALSO, explain how to identify an adverb and a preposition.

Answer 1

Explanation:

Words that are sometimes prepositions can act as adverbs. A preposition requires an object. An adverb does not. A single word acting as an adverb answers where, when, how or to what degree about the verb.

Answer 2

Answer:

An adverb is a word that modifies (describes) a verb (he sings loudly), an adjective (very tall), another adverb (ended too quickly), or even a whole sentence (Fortunately, I had brought an umbrella). Adverbs often end in -ly, but some (such as fast) look exactly the same as their adjective counterparts.

Whereas,Prepositions and postpositions, together called adpositions, are a class of words used to express spatial or temporal relations or mark various semantic roles.
