Hello,

1.I am attendeing the meeting like/as an observer.

2. I use one of the bedrooms as/like an office.

3. I want to qualify as /like an enginner.

What is the correct choice between (as/like).

I refred the dictionary and it tells that "as" and "like" both can be used as preposition. So I got confused when to use "like" and "as".

Some where it written --

4. He works as a doctor. why not "He works like a doctor."

Thanks.

Generally, as means that something is. Like means that something is similar.

He works as a doctor. That's what work he does, he's a doctor.

He works like a doctor. He isn't a doctor, but he works in a way similar to that of a doctor.

Awesome explaination... I was struggling to understand the basic diff earlier..Thnx for clearing it
Like (when used to mean "similar to") is a preposition. As (when used to mean "in the same manner") is a conjunction. Prepositions govern nouns, pronouns, and words used as nouns. Conjunctions join clauses.

So, "Like Pan, I'm an orangatan."
But, "Pan behaves as a good orangatan should behave."

Basically, if a subject and verb are to follow, use "as." If a single word follows, use "like."

Of course, in common speech, people use these words interchangeably.

1. I use one of the bedrooms as/like an office. use LIKE (Bedrooms Noun)

2. I want to qualify as /like an enginner. use AS (Qualify Verb)
