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.

Hello Ajay007,

I'm supposing what you mean is 'You looked as if you'd just seen a ghost'. In this case, 'have just seen' is not correct because a present perfect form doesn't coordinate with the past time of the past simple verb 'looked'. Instead, we use a past perfect form, which refers to a time previous to the one indicated by the past simple.

If you meant something else, please provide the specific sentence you're asking about.

Hi teachers,

I saw one example sentence from the University of Cambridge (from their dictionary) which is: 'The floods were rising and it was as if it was the end of the world.'

Could you please explain why we dont write '... as if it HAD BEEN the end of the world.' instead?

Thank you very much!


Hi Dung,

Had been (past perfect) shows that the action (the end of the world) happened earlier than the other past action. However, in this sentence, the rising floods themselves are what seem like the end of the world (i.e., it is at the same time as the floods). Does that make sense?


The LearnEnglish Team

I am not a teacher but I've noticed something it might help or not. Anyway, it says 'You LOOK as if you HAVE seen a ghost.' and the other example is 'The floods WERE rising and it WAS as if it WAS the end of the world.'

The first verbs give an idea about the time they were talking about so I believe we can understand the time and continue with a needed time.
But of course this is my idea it might be wrong as well. I reckon we need to look for more examples.

Hello zahra khawari,

That sounds like a great plan. I'd suggest you start working in our Skills section, where you can find lots of materials at different levels. If you already know your level, you can start with the materials at that level; if you don't know your level, try out quick level test ( As you work, if you find it too difficult, try a lower level; if you find it very easy, try a higher level.

You might also want to consider our Online courses (, where you can choose from several paid options.
