	who / that

	OBJECT of MOD CLS
The woman	You called the woman	is my friend.
	who / whom / that
The woman	who(m) you called whom you called	is my friend.

SUBJECT	SUBJ of MOD CLS
The woman	who called you She called you.	is here.
The woman	*that called you She called you.	is here.

WHOM – OBJECT OF THE CLAUSE
The who(m)–clause is placed directly after the personal noun that it modifies. The object pronoun can be omitted.

	OBJECT	OBJ of MOD CLS
Here is	the woman	who(m) you called You called her.
Here is	the woman	*that you called You called her.

SUBJECT PRONOUN OF CLAUSE
When who takes the place of the subject noun/pronoun in a modifying clause, it cannot be omitted (deleted).
The guy who is talking is the leader. — The guy is talking — (subject)
The doctor who looked at my arm was young. — The doctor looked at my arm— (subject)
Two girls who rang my doorbell sold me cookies. — Two girls rang my doorbell — (subject)

When who takes the place of the object noun/pronoun in a modifying clause, it can optionally be omitted (deleted).
The guy (who) you spoke to is the leader. — you spoke to the leader — (object)
The doctor (who) I preferred was young. — I preferred the doctor— (object)
Two girls (who) I chatted with sold me cookies. — I chatted with two girls — (object)

FOLLOWED BY A VERB
If the relative pronoun is followed by a verb, then the relative pronoun is probably the subject of the clause. It cannot be deleted.
The guy — who showed us his car — seems fair. — who → verb — (It's likely the subject.)
The driver — who hit his car — is apologetic. — who → verb — (It's likely the subject.)
The girl — who lives next door — drives a Honda. — who → verb — (It's likely the subject.)

FOLLOWED BY A SUBJECT NOUN / PRONOUN
If the relative pronoun is followed by a subject noun or pronoun – I, we, he, she, they – then who is probably the object and it can be deleted.
The guy –– who we spoke to — seems fair. — who → we… — (It's likely the object.)
The driver –– who she ran into — is upset. — who → she… — (It's likely the object.)
The man — who you met — drives a Jeep. — who → you… — (It's likely the object.)

IDENTIFYING CLAUSE
A clause that identifies the noun before it (tells you which one) is not set off with commas.
The man that lives next door is a marathon runner.
Jack hired the gardener (whom) you recommended.

NONIDENTIFYING CLAUSE
A clause that adds extra, nonidentifying information is set off with comma(s). The object pronoun cannot be omitted.
Jack Trainer, who lives next door, is a marathon runner.
Jack hired Mr. Lee, whom¹ you recommended.

AT END OF CLAUSE
When the verb accepts an indirect object, the object preposition is likely to occur at the end of the clause. Leaving the preposition at the end may be considered informal use.
The police officer whom I gave my passport to took down my information. I gave my report to the officer.
The police officer who I gave my passport to took down my information.
The police officer that I gave my passport to took down my information.
The passport which he was looking at had expired the week before.
The passport that he was looking at had expired the week before.

BEFORE THE RELATIVE PRONOUN
When using whom or which, a preposition belonging to the indirect object may be placed before the relative pronoun. This is formal use (academic and business).
The police officer to whom I gave my passport took down my information. I gave my report to the officer.
The police officer *to who I gave my passport took down my information. (Use whom.)
The police officer *to that I gave my passport took down my information. (Use whom.)
The passport at which he was looking had expired the week before.
The passport *at that he was looking had expired the week before. (Use which.)

ERROR	SOLUTION
*The guy is here who wants to play football.	The guy — who wants to play football — is here. The who-clause must be next to the word it modifies.
*The man which you are talking about isn't a friend.	The man whom/ who/ that you are talking about isn't a friend. Which is not used as a personal pronoun for a person. Use that.
*There's a man on the phone wants to talk with you. missing relative pronoun	There's man on the phone who wants to talk to you. A subject pronoun cannot be omitted.
The man whom I believe lives next door to you is a pilot.	The man who, I believe, lives next door to you is a pilot. The man who lives next door to you is a pilot, I believe. I believe, the man who lives next door to you is a pilot.
