A word or phrase that modifies a word not included in the sentence is a dangling modifier.
Here is an example:
<em /><em>Hungry, the leftover pizza was devoured.
</em><em />You can see that the word <em>hungry </em>refers to <em>us, </em>but <em>us </em>is not included in the sentence. The way it is written, it would seem that <em>hungry </em>refers to <em>pizza, </em>which is wrong.
