Hello, FionaB,
Is knock out a type 3 phrasal verb in this context?
Do you know anyone who's been knocked out?
If so, is anyone the object, and does that mean a type 3 phrasal verb can have the object before the verb?
I thought type 3 phrasal verbs had the form
verb + particle + object or
verb + object + particle,
but I've never seen the form stated such that it can be object + verb + particle.
I'm not sure what you refer to by "type 3 phrasal verb."
"Knock out" is a transitive phrasal verb of the kind you mention, insofar as object nouns can appear before or after the adverbial particle, while object pronouns can only come afterwards:
- Joe knocked Donald out.
- Joe knocked out Donald.
but
- Joe knocked him out.
The point with your sentence:
- Do you know anyone who's been knocked out?
is that it is in the passive voice, with the object (anyone) becoming the subject. As a result, the object will appear before the verb as subject.
- Donald was knocked out.
The fact that the phrasal verb is in the passive voice does not change its grammatical nature.
