Question

They were blinded by a dust storm. They fell into disorder​

Answer 1

A participle is that form of the verb which partakes of the nature of both of a Verb and of an Adjective. It is also called a Verbal-Adjective. And a phrase which is introduced by a participle is called a participial phrase.

In this sentence, 'blinded' is the past participle and the phrase that it governs is 'blinded by a dust storm'.
