The passive the causative direct and indirect objects
Only Transitive Verbs Have Direct Objects and Indirect Objects A verb that takes a direct object is called a transitive verb. A few verbs do not have a direct object. They are known as intransitive verbs. For example: Jonathan skidded on the ice.
Step 1. Find the verb = "skidded"
Step 2. Ask "What?" = Nothing. You can't skid something.)
(Therefore, there is no direct object. The verb "to skid" is intransitive.)
Step 3. We can't do Step 2 if there's no direct object. Let's look at another one:
Lee is snoring heavily.
Step 1. Find the verb = "is snoring"
Step 2. Ask "What?" = Nothing. You can't snore something.)
(Therefore, there is no direct object. The verb "to snore" is intransitive.)
Step 3. We can't do Step 2 if there's no direct object.
