Educating the pass

We hear a lot about how to receive the ball. how to create space, how to move to the ball, body shape etc..
What about information on where the bass should be?
Is is to feet?
Is it safe side? ( Do you know what that means?)
Is it into space?
Which foot are you passing to?
What is the weight of pass?
Can your team mate deal with the pass?
Do you have a signal?
Have you read a signal ?
YOU have the ball.. ????
