Could someone please tell me which transitive verbs can form notional passives? I only know that they are usually formed with intransitive active verbs.
A notional passive is an active, normally transitive verb that is used with a passive 'meaning'. It is not an actual passive verb, but it resembles one. In general, there is no limit to which transitive verbs can be used with a notional passive; in many cases, you could apply it to new verbs. It does look informal with verbs that are not commonly used this way.
People read this sentence without effort.
This sentence is read without effort. — [passive]
This sentence reads well. — [active, but notional passive]
It could be defined as a verb that is syntactically active but has its subject in the semantic role of a patient—or any other role normally occupied by the object of the verb when it is active.
