This is covered in Harbrace 25b: Revise Dangling Modifiers
Although any misplaced word, phrase, or clause can be said to dangle, the term dangling modifier applies primarily to incoherent verbal phrases and elliptical clauses (that is, clauses with implied subjects and verbs) that do not refer clearly and logically to other words in the sentence. To correct a dangling modifier, rearrange the words in the sentence to make the modifier clearly refer to the right word, or add words to make the meaning clear and logical.
When verbal phrases or elliptical clauses come at the beginning of a sentence, the normal English word order requires that they immediately precede and clearly refer to the subject of the sentence.
Turn to Section 25 of Harbrace for excellent illustrations of the many kinds of dangling modifiers.
Below is an example of a related problem, a subject with an imprecise or unclear antecedent.
