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 sir. I come across both "as planned" and "as was planned", "as expected" and "as was expected" while reading. Are they all acceptable? If so, any difference? And why is "as planned" grammatically correct, given that there seems no predicate in "as planned"?

Thank you for your time.

Hi Radioheady,

Yes, all these are acceptable, and there is no difference in meaning. 

This is the passive (be + past participle) reduced by deleting "be". After "as", the present and past simple passives can be reduced in this way (similar to how they can be reduced in a relative clause, e.g. The picture shown here = The picture which/that is shown here).

So in order to check I’ve understood everything. In the following situation…
I see it as an opportunity to learn
I see it like an opportunity to learn
Would you use “as” because you are talking of a function? Or do you use both because like can be used + a noun?
Thank you in advanced!

Hello Cmae,

'see it as' is the correct option here. When we're talking about how we see or view a situation, we use 'as'.

It is possible to say 'see it like', though, when 'like' means 'in the same manner' as another person -- for example: 'I don't see it like he does'.

All the best,

The second game didn’t go as …….. as the first one
a) good
b) well
C) better
D) best

Hello unkonwn,

'well' is the answer. You're comparing how the two games went and so you need an adverb. This is a comparative structure, but the basic form of the adjective or adverb is used with 'as ... as'.

Best wishes,

Hi, Can I rewrite the sentence like this?
My mother is the most warm-hearted person I've ever known.
-> I have never known such a warm-hearted person like my mother.
'such' is for emphasis (such a good film), 'like' in similar to, in the same way as (a warm-hearted person like my mom), not such as the fixed phrase.
Thank you!

Hello Uyen123,

No, I'm afraid not. After 'such' you need to use 'as': (such a.... as....) and you can't replace it with 'like'.

Hi Peter, Thank you for you reply. But i'm still a bit confused.
In Cambridge Dictionary, such (1st meaning): used before a noun or noun phrase to add emphasis. Such ... as is in the 2nd meaning if such: of the particular or similar type. I feel like 'like' can be replaced and understood as similar (1st meaning)
- I've never met such a warm-hearted person like/ similar to my mother.
Thanks for your clarification.

Hi Uyen123,

Like shows similarity but does not directly compare two things in terms of degree. For that kind of comparison you need such as. In fact, 'as' is key for showing degree and you can see it in many phrases: as big as / so big as / such a big thing as.
