What is the difference between nominative and passive?

The transformation from active to passive

Active sentence with accusative

A passive clause is created by transforming an active clause with nominative and accusative.

Example:
Active: The student asks the teacher.
Passive: The teacher is asked (by the student).

You can see that the nominative, accusative and verb of the active sentence change as follows:

Active passive
Nominative: the student - from + dative: from the student
Accusative: the teacher - Nominative: the teacher
Verb in active: asks - Verb in passive voice: is asked

The conversion rule from active to passive is:

Active passive
Nominative - from + dative
Accusative nominative
Verb in active - verb in passive

Active clause with accusative and dative

If the active sentence contains a dative in addition to the accusative, the dative remains unchanged.

Example:
Active: The man gave the woman a book
Passive: The woman was given a book by the man.

Active clause without accusative (subjectless passive clauses)

You can also form passive if there is no accusative in the active clause, but only a nominative, dative or prepositional addition. The passive clauses that arise from the transformation of active clauses without the accusative are also called subjectless passive clauses. Subjectless passive sentences are usually less recommendable stylistically.

Example: active sentence (only) with nominative
Active: He is working.
Passive: By him is being worked.

Example: active sentence with dative
Active: the doctor helps the woman.
Passive: The woman is helped by the doctor.

Example: active sentence with preposition
Active: a woman scolds about the politicians.
Passive: from a woman becomes about the politicians scolded.

Active sentence with man

If a passive clause comes from an active clause with man is derived, the passive sentence never contains an agent specification of + Dative.

Example: active sentence with accusative
Active: You ask the teacher.
Passive: The teacher is asked.

Example: active sentence with accusative + dative
Active: the woman is given a book.
Passive: The woman is given a book.

Example: active sentence with dative
Dative: You help the woman.
Passive: the woman is helped.

Example: active sentence with preposition
Active: You scold the politicians.
Passive: The politicians are scolded.

Example: active sentence only nominative
Active: You work.
Passive: Work is in progress.

Temporal accusative

Note: Not all accusatives in the active clause can be converted into a nominative in the passive clause. The accusative remains unchanged if it does not refer to a person or thing, but to time (temporal accusative).

Example:
Active: the child was playing all day.
Passive: All day was played by the child.
