Words like "read", "wind", "live" and "lead" are spelt the same, but have different meanings:
Lead1 (leed):
cause (a person or animal) to go with one by holding them by the hand, a halter, a rope, etc. while moving forward.

and
Lead2 (led):
A heavy, comparatively soft, malleable, bluish-grey metal.

So what are these words called? And are there any others, beside the 4 I have mentioned?
