“Like” vs. “As”

The words like and as are used for comparisons, but people often use the word like for all comparisons, instead of using the appropriate word for each circumstance.

Like is a preposition that should be used to compare two nouns or noun phrases, and is used like an adjective (to modify one noun and show its comparability to another noun.

As, on the other hand, is a conjunction that is used to connect and compare verbs or verb clauses, and is used like an adverb (to describe or compare the manner of an action being taken).


  • “To John, his cell phone is like a piece of sports equipment — one day and the screen’s already cracked.”
  • “John treats his cell phone as he treats his baseball glove — toss it on the floor when he’s done. No surprise it’s so scratched up.”

Just remember, whenever you’re comparing actions, use as instead of like:

  • Although many adults think modern pop music is like the product of a marketing committee pandering to poor taste, modern pop music isn’t any worse than it was 30 years ago: young people simply have different tastes from adults, as they always have.

The difference between like and as is tested on the SAT, ACT, GMAT, and GRE. Knowing proper grammatical style can help you in daily life, in your professional life, and on standardized tests. If you are planning to take any of these tests, contact Bobby Hood Test Prep for more information!
