pls tell me the difference b/w 

few,a few and a little.

Dear Student,

1. Few or little (without 'a') describes a a more negative idea.

For example:

Be quick. There is little time (i.e. there is not enough time)

I have few friends (i.e. not many friends)

2. A few, a little are used to describe more positive ideas.

For example:

Let's pack this too. We have got a little time before the bus leaves. (i.e. some time)

I have a few chocolates. (i.e some chocolates)
