THREE RHYMING RIDDLES

1)

If you throw me out the window,

I will leave a grieving wife;

Bring me back, but in the door,

You'll see someone giving life.

Who am I?

2)

My first is in west, but not in east,

My second in east, but not west;

My third and fourth are in both of these.

For my fifth, however, you will look in vain,

In west or east or south.

A word of five letters, my whole comes forth

When you look in the middle of north.

3)

I begin with sixty-four,

But finish with just one;

The competition's fierce,

Though in theory it's just fun.
