Answer: Alike: type of word
Different: Meaning and function in a sentence
Step-by-step explanation:
They are alike because both are nouns. Take the following sentences as an example:
1. John went fishing at the lake last year. (Here, the word is used as an ADVERBIAL OF PLACE)
2. Smoke poured out of the floor-to-ceiling windows. (Here, the word is used as SUBJECT).
However, smoke can be used as a verb. For example:
1. Oh, Anna is always smoking!
On the other hand, lake can only be used as a noun.
Of course, both have differences in meaning:
A lake is a body of water of considerable size
A smoke is visible vapor given off by a burning sustance OR the action of giving off smoke.
