I stumbled across are a weird collection of verbs that are specific in usage that MUST have a categorization but I don’t know what it is. When students first learn parts of speech they learn that verbs are “things you can do!” or “action words!”. These verbs however have no active form.
Throb: Something can throb, but I can’t throb something.
Itch: Something can itch, but I can’t itch something.
It’s more than just a passive verb – because the active form of the verb doesn’t exist. Does anyone know what this is called? Can anyone think of more examples?
