Adverb:
* Meaning: In a similar way or manner
* Example: "She walks like a dancer." ("Like" modifies the verb "walks")
Preposition:
* Meaning: Similar to, resembling
* Example: "He looks like his father." ("Like" introduces a prepositional phrase that modifies the verb "looks")
Here's a way to tell the difference:
* Adverb: If you can replace "like" with "similarly" or "in a similar way", it's likely an adverb.
* Preposition: If you can replace "like" with "resembling" or "similar to," it's likely a preposition.
