What is the difference between as vs like? When to use one

Question

What is the difference between as vs like?
When to use one against the other in GMAT?

mmapplebeck · Answer

Do you mean  such as  vs.  like ?

In GMAT Sentence Correction, such as is used to introduce examples, while "like" indicates only similarity and cannot be used for examples at all. Let's take a look at the following sentences:

1) I enjoy playing sports such as football and baseball.

2) I enjoy playing sports like football and baseball.

In the first sentence, we know that football and baseball are specific examples of sports the author enjoys. In the second sentence, however, all we can glean is that the author enjoys sports that are similar to football and baseball (rugby and cricket perhaps?). Whether either sentence is correct depends on the context. If football and baseball are meant as specific examples, sentence 2 is incorrect because "like" does not introduce examples.

This rule is becoming increasingly obsolete in modern American English, but it still must be followed in GMAT Sentence Correction problems.

No. I mean the difference between as vs like.
When to use one over the other?

He took a decision like his father.
He took a decision as the chairman of the board.

Is there any rule of thumb?

Zynga · Answer

Like  - used to compare two nouns.

Incorrect - John and Jane, as their mother Cathy, are extremely smart.
Correct - John and Jane, like their mother Cathy, are extremely smart.

As  - used to compare two clauses.

Incorrect - Just like swimming is good exercise, running is a way to burn calories.
Correct - Just as swimming is good exercise, running is a way to burn calories.

Note : You cannot use " Like " when you mean for example

nkimidi7y · Answer

Thanks Zynga.
That was spot on.

So to sum it up.

Like to compare two nouns.
As to compare two nouns with two actions.

Like cannot be used as example. We should instead use "such as".
Thanks for the clear and concise explanation.

Keep in mind when using 'as' that it needs to have a working verb (since its a clause):

Macauley swims well, as her brother DOES.
If you see the same sentence with 'like' see if you can find a verb after it. If you do, then its wrong.

Also another use of 'like' and 'as' appears in the form of idioms:

Like: is used to compare two things symbolically or metaphorically
eg. The stars in the night sky look like diamonds.

As: is used to compare things functionally:

The cement acted as a glue keeping the bricks together.
Here the cement is functioning like glue and the appropriate use is as.

So remember symbolic vs function : : like:as

In your example:
He took a decision as the chairman of the board.

He took a decision as the chairman of the board. (since there is no verb after 'as' this is an idiomatic construction)

If for instance we used like: He took a decision like the chairman of the board. 
This would change the meaning of the sentence altogether.

The single easiest way I found to distinguish between the two of them is to understand if there is a verb the stem is referring to or not.

As can be used with a verb

Like can not.

This is the most basic idea you should get.
If I am not wrong, obviously. :roll:

Here is another way to look at it:

Like = Similar

As = Same

Now no 2 people or things can ever be the same. But their behavior, or action can be. For example:

Like his brother Joe, David too is taking the GMAT this year.

David is putting in 2hours every day towards the prep just as his brother Joe did.

Caveat: You can compare 2 nouns using "as" if your intent is both of them are the same.

Bruce, as Batman, kept a vigil over Gotham.  (Bruce stood vigil because he was Batman)

Brian, like Batman, kept a vigil over Gotham. (Brian stood vigil just as Batman would have)
