1. Comparative Clauses:
* Definition: A comparative clause compares something to something else.
* Example: "The dog looked like he had been dragged through a mud puddle."
* Explanation: "Like he had been dragged through a mud puddle" is a comparative clause because it compares the dog's appearance to someone being dragged through mud.
* Comma Rule: Use a comma after "like" when introducing a comparative clause.
2. Parenthetical Phrases:
* Definition: A parenthetical phrase adds extra information that could be removed without changing the sentence's meaning.
* Example: "I went to the party, like I said I would."
* Explanation: "Like I said I would" is a parenthetical phrase because it adds extra information about the speaker's previous statement.
* Comma Rule: Use a comma before and after "like" when it introduces a parenthetical phrase.
Here are some examples:
* Comparative Clause: "The house is like a castle."
* Parenthetical Phrase: "I went to the store, like I always do on Tuesdays."
Important Note: "Like" is often used incorrectly without a comma when it introduces an example. This is a common grammatical error. For example, "I like many things, like pizza and ice cream." This sentence should be revised to: "I like many things, such as pizza and ice cream."
Remember: If you're unsure whether to use a comma with "like," try reading the sentence aloud. If the phrase after "like" is a comparison or adds extra information that could be removed, then you likely need a comma.
