LOOK

FOR

What are you looking for?

I am looking for a job

FOREWARD

I'm looking forward to hearing from you again

BACK

I'm looking forward to hearing from you again

AROUND

Let's take a look around

I am not sure if I know what is going on

ON

But people here already seem to be looking on the dark side.

We're not related, but I've always looked on him as my brother

AT

Look AT that beautiful building at the end of the street

UP

Our business is looking up = it is getting better and better

You should look this word in a dictionary as I do not know the meaning

to visit someone after a long time

She had always looked up to her older brother

DOWN

Do not look down as you may feel dizzy

to be sad or depressed

OUT

Look OUT!!!

Look OUT through the window

THROUGH

You do actually have to look through to see the light coming out!

I have to look through my husband`s mobile
