Equivocation

From Atheism

Equivocation is a logical fallacy where a term changes its meaning in the course of an argument. Wikipedia gives the following example.

A feather is light. What is light cannot be dark. Therefore, a feather cannot be dark.

We all know that for example a crow’s feather is dark. In this case “light” changes its meaning. First light means, “Not heavy”. Later “light” means bright.
