Using 'like' as a conjunction
Some people and older grammar books state that it is incorrect to use 'like' as a conjunction but it has been common in everyday, informal situations for a long time. Both of these are correct:
Our new Sodasport is light, and refreshes like a sports drink should.
Our new Sodasport is light, and refreshes as a sports drink should.
'As if" and 'as though'
These are conjunctions which we use to make comparisons. They have the same meaning and are used to talk about situations that are imaginary, possible or likely. They are often used with verbs like 'look', 'feel', 'sound', 'seem' etc.
The meeting was so boring - it felt as if it would never end.
It looks as though we'll have to work late again tonight.
It sounds as if it's raining out there.
I don't know why she isn't speaking to me; it's not as though I've done anything wrong.
In the examples above, we can also use 'like', although this is considered conversational and is best avoided in formal contexts.
We can also use these before an infinitive or a prepositional phrase. In these kinds of sentences, we can't use 'like':
He looked at me across the table as if to say, 'Please don't disagree with the client!'
I was embarrassed by them. They were behaving as though at school.
Choosing between 'as' and 'like'
Meaning
In the tables above you can see that sometimes the choice of word changes the meaning.
| He works as an ecologist. | [This is his job.] |
| He works like an ecologist does. | [His job is similar to that of an ecologist.] |
| As your mother, I promise I'll always be here for you. | [The speaker is the listener's mother.] |
| Like your mother, I promise I'll always be here for you.
| [The speaker is making the same promise as the listener's mother did.] |
Formality
If both words have the same meaning, then consider the formality. 'As' is sometimes more formal than 'like'.
It was as though she wanted to lose the debate.
It was like she wanted to lose the debate. [informal, conversational]
