And there is amphiboly when modifiers are misplaced, such as in a famous Groucho Marx joke: One morning I shot an elephant in my pajamas. If we translate the premise, well see that the arguer has really just said the same thing twice: decent, ethical means pretty much the same thing as morally acceptable, and help another human being escape suffering through death means something pretty similar to active euthanasia.

The equivocation here is on the word right: right can mean both something that is correct or good (as in I got the right answers on the test) and something to which someone has a claim (as in everyone has a right to life).

Fallacies of ambiguity and grammatical analogy occur when one attempts to prove a conclusion by using terms, concepts, or logical moves that are unclear and thus unjustifiably prove their conclusion because they're not obviously wrong. Example: Giving money to charity is the right thing to do. That is, correlation isnt the same thing as causation. You did it, too!
