14. Get passive vs. be passive
The passive with GET
get + past participle
Get is often used instead of be in the passive voice in informal spoke
English to refer to an action that happens by accident or unexpectedly:
• Their car got stolen in front of their house last night.
Jerry got fired because he was always late for work.
Get expresses action and change and is only used with action verbs,
not state verbs:
• Jerry was fired because he was always late for work.
Jerry got fired because he was always late for work. (fire is an
action verb)
• Nothing is known about the thief.
Nothing gets known about the thief. (know is a state verb)

15. As get in the passive voice expresses action, it makes it
possible to differentiate between an action and a state
if it is not otherwise clear:
• The living room window was broken. (state or action)
The living room window got broken. (action)
The passive with be and the agent mentioned also makes
the distinction clear:
• The living room window was broken by the burglar.
(action)
A reflexive pronoun after get indicates that the recipient
of the action is in some way involved in or responsible
for what happened:
• He got injured while playing football. (it was an
accident)
He got himself injured while trying bike stunts. (it was
partly his fault)

16. The get passive is also used in certain idiomatic
expressions:
Idiomatic expressions with the get passive
• get dressed
get washed
get engaged
get married
• get divorced
get lost
get mixed up
get started
• I took a shower and got dressed.
When did they get married?
Have you ever got lost while travelling?
