Who and whom practice

USE WHO OR WHOM DEPENDING UPON THE FUNCTION IN THE SENTENCE. Who and whoever should be used when a subject or subjective complement is needed.
Whom or whomever are used as the objects of prepostions or when the pronoun is a direct or indirect object.
To determine which one to use to begin a question, see if there is another word in the question functioning as the subject. If not, pick who.Example: Who could narrate such a story? No noun or pronoun functioning as subject.
Whom did you visit? You is subject, so pick whom.
If you are trying to decide which one to use to begin a dependent clause, check and see if there is another word in the clause that is functioning as a subject. If not, choose who. If there is, choose whom.
The president was not whom SHE had expected. SHE is the subject, so choose WHOM.
Richard feels like a knight who is on an adventure. No subject, so choose who
Another trick is to answer the question or substitute a pronoun. If the answer is a nominative case pronoun (he, I ,she , they), use who. If you can substitute nominative case pronoun at the beginning of the clause (he, I ,she , they), use who.
