Grammar explanation

as and like are often confused since they can both be used for comparisons. There are, however, important differences.

Making comparisons

as + adjective + as and as much as

We often use the structure as + adjective + as or as much as to say if something has, or doesn't have, the same amount of that quality as something else. 

She loves curry as much as I do.
He's not as tall as his brother.
It's not as expensive as the other hotel.
That dog is as big as that child!

You also have to use as in the expression the same as.

Your phone is the same as mine.
Texting is not the same as speaking in person.

like + noun

In the following comparisons, like is followed by a noun or a pronoun to say that two things are similar.

He's like a father to me.
She's acting like a child.
It's like a burger but with big mushrooms instead of bread.
There are lots of people like us.

It is also common to make comparisons using like with verbs of the senses.

She looks like her mother.
It sounds like a cat.
Nothing tastes like homemade lemonade.
It smells like medicine.
It feels like cotton.

as if/as though + clause

As if and as though can be used to compare a real situation to an imaginary situation. They are followed by a clause (a subject and verb).

You look as if you've seen a ghost.
I felt as if I was floating above the ground.
You talk as though we're never going to see each other again.

Giving examples

We can say like or such as to give examples. 

You could try a team sport like football, basketball or hockey.
You should take something soft, such as a towel, to lie on.


Talking about a job or function

We can use as + noun to talk about a job or function. 

I worked as a shop assistant for two years.
He used his coat as a blanket to keep warm.


as to connect two phrases

as can be used as a conjunction to connect two phrases. It can have different meanings.

as = 'because'

All the tickets were sold out as we got there too late.
As the road was closed, I had to park on the next street.

as = 'while' or 'during the time that'

She called as I was getting out of the bath.
As they were arriving, we were leaving.

as'in the way that'

As we expected, it started to rain.
As you know, classes restart on 15 January.
As I said, I think this project will be a challenge.

** Note that in informal speech, people sometimes say like for 'in the way that'.

Like I said, I didn't know her.

Hi English Team, I am so glad to find out this page. It seems so useful to improve my English skills. And I have some questions: 1. The ice cracked as I stepped onto it. --> Could I use "when" instead of "as"? 2. He jumped to his feet as the boss came in. --> Could I use "when" instead of "as"? 3. As they were signing the contract, they noticed that a page was missing. --> Could I use "when" or "while" instead of "as"? Thanks a lot.

Hi Sunyoung1005,

Thanks for your kind comment :)

Yes, all three sentences work with both as and when. Both words show actions happening at the same time.

There's a small difference: when can also show actions happening one after the other (i.e. not at the same time). So, if one action caused the other one to happen, when is a good choice, and I slightly prefer when in sentences 1 and 2. But, we can also think of those actions as happening at the same time, so as is fine too.

In sentence 3, using while suggests that signing the contract had some duration (i.e. it took some time).

Best wishes,

Thanks for your detailed reply teacher. Regarding sentence 3, I also have the feeling that using "while" would suggest the signing of the contract had some duration. In sentence 3, is it correct to say "as" or "when" would be better than "while", although the latter is not grammatically correct?

No worries. All three words (whilewhenas) are grammatically correct in sentence 3. I don't think we can say which one is best – it just depends on how you want to represent the situation.

While shows that the action had duration, as you say. You can use this if you want to show clearly that one action happened in the middle of the other (noticing the missing page happened in the middle of signing).

If you just want to show that the two actions (signing and noticing the missing page) happened at the same time, as and when both work.

So, there's a small difference in meaning! But I guess that in most situations, this difference would not be important.

I hope that helps.

Best wishes,

Hi Sir, 1. "This is as exciting as I had imagined." - Why is the past perfect tense used instead of the simple past tense? 2. "You spent more money than was intended to be spent." - Could I say "...than intended to be spent" instead? Thanks Sir.

Hi cms10,

1. It's hard to be sure without knowing the context of the sentence. However, I would guess that the speaker is referring to a time before they tried whatever it is they are talking about. Thus you have three time references:

> now - it is exciting

> past - I started the activity

> further past - before I started the activity


2. No, that does not work. If you want to use the active form (intended) rather than the passive (was intended) then you need to be consistent and use an active verb following it (to spend not to be spent). You also need to include the subject:

You spent more money than you intended to spend.

Hello English Team, 1. the books as listed below. - I saw this sentence on a website about the use of "as". It says "the books as listed below" is different from "the books listed below" but without giving an explanation. Could you tell me the difference between the two? 2. "She felt a great sense of pride as she watched him accept the award."; "The companies have upgraded their networks to improve their capacity as data traffic increases." - In these two sentences, could I replace "as" with "when"? Thanks a lot teachers!

Hello Kashvi.la27,

In this context 'as' means something like 'in the way'. Thus, 'listed below' tells us simply that the books are below the text. 'As listed below' would suggest a method or way of doing something. In the context of listing books for reference I don't think the difference is really important, but it would be important if, for example, the sequence were crucial for some reason.


As a time marker, 'as' tells us that one event occured simultaneously with another event; this would include one event occuring while another event is in progress. 'When' suggests that either the two events started together, or


She felt a great sense of pride as she watched him accept the award.

Replacing as with when changes the sentence somewhat. As tells us that she felt pride during the process of his accepting the award. When tells us that the event of his accepting caused her to feel pride. It doesn't tell us that she felt pride during the event (though she may have).


The companies have upgraded their networks to improve their capacity as data traffic increases.

Again, as here tells that the improvement takes place during the increase. Data traffic may increase every day and the improvement will keep pace with this. When would tell us that we expect an increase in data traffic at some point and the capacity will improve at this moment.

Thank you for your reply teacher. You said "'When' suggests that either the two events started together, or" - May I know whether you accidentally deleted the second part of the sentence? "She felt a great sense of pride as she watched him accept the award." - Regarding this sentence, when I saw this sentence, I thought "when" was a better choice because her feeling was caused by her watching him accept the award, whereas "as" does not convey the meaning of a causal relationship. Is this analysis of the sentence correct?

Hello again Kashvi.la27,

It seems the second half of the sentence was deleted by mistake. The full sentence was this:

When suggests that either the two events started together, or that one began immediately after the other began, possibly because it was caused by the first event.


Ordinarily, when would emphasise the possibility of a causal relationship, as you say. However, the particular context of your example makes the causality self-evident already. Given this, the choice is really whether you want to emphasise that the pride was felt during the receiving of the award or as a result of the receiving. The first (with as) suggests that the whole process - the ceremony etc - creates the woman's pride. The second (with when) suggests that it is the achievement - the actual award itself - which creates the woman's pride.
