What's the difference between a preposition and a participle?

Question

See title. I really have nothing else to add!

Answer 1

A preposition is a word used before a noun to add a context. (in, at, etc.)

A participle is a form of a verb. It can either be a present participle (dancing), or past. (danced)

Answer 2

To add to Eldros' answer, here are a couple references:

Preposition

Participle

A participle is usually used as an adjective, which is one of the greatest strength of the English language: the ability to take a verb and turn it into an adjective or a noun as necessary.

Answer 3

A participle is a word formed from a verb and used as an adjective or a noun.

• working
• being
• burned

A preposition is a word governing, and usually preceding, a noun or pronoun and expressing a relation to another word or element in the clause.

• of
• for
• on
• after
