<p>“Lisa is as smart as her/she?”</p>
<p>“she” is right; the pronoun is performing the action of being smart.</p>
<p>“Neither of them is/are available to speak right now.”</p>
<p>“neither” is always singular, so the correct choice is “is.” The prepositional phrase that follows “neither” is irrelevant.</p>
<p>Here’s my nearly comprehensive guide to subjet-verb agreement, which should help you:</p>
<p>SUBJECT-VERB AGREEMENT</p>
<p>I. Coordinating Conjunctions</p>
<ul>
<li>AND - When “and” is used to link two noun phrases, the verb is always plural.</li>
</ul>
<p>Examples: He and I are hungry. The book and the dog are yellow. The hippos and the monkey are extinct. There are a goldfish and a hamster in my pants.</p>
<p>When “and” is used to link two nouns so that a collective noun is formed, the verb is singular.</p>
<p>Examples: Macaroni and cheese tastes like food. </p>
<ul>
<li>OR - When “or” is used to link two noun phrases, the verb matches the subject closest to it. </li>
</ul>
<p>Examples: The dog or the preparatory book is going to be my dinner. The desks or the ceiling is going down at 3:00. The water or the dinners are happy. There is a clock or bananas under the floorboards. There are bananas or a clock under the floorboards. </p>
<p>II. Correlative Conjunctions</p>
<ul>
<li>EITHER ___ OR, NEITHER ____ NOR - The rule for these conjunctions is similar to that stated above for “or:” the verb agrees with the closer subject.</li>
</ul>
<p>Examples: Either the happy soup-maker or his watches are upset. Either the chap-sticks or the cube is round. Neither the ceiling nor the floor is around me. Neither the floors nor the walls are in this sentence. </p>
<ul>
<li>BOTH ___ AND - This construction always results in a plural verb.</li>
</ul>
<p>Examples: Both the word and its letters are about to be written. Both the hat and the head are flubber. </p>
<p>III. Indefinite Pronouns</p>
<ul>
<li>EACH, EITHER, NEITHER, MUCH, -ONE, -BODY, -THING - These pronouns always agree with singular verbs; the intervening prepositional phrases are irrelevant.</li>
</ul>
<p>Examples: Each of you is a winner. Neither of them is happy. Much of the student body is living. Everyone is supper. Nobody is under fire. </p>
<ul>
<li>FEW, OTHERS, MANY, BOTH, SEVERAL - These pronouns always agree with plural verbs; the intervening prepositional phrases are irrelevant.</li>
</ul>
<p>Examples: Few of the people are dead. Others are awake. Many of the colors are non-existant. Both of you are hard-working. Several of them are not.</p>
<p>-SOME, ANY, ALL, MOST, NONE - These pronouns’ agreement varies based on the referent, usually found in the intervening prepositional phrase; they can be either singular or plural. If the referent is singular, the verb is singular; if the referent is plural, so is the verb.</p>
<p>Examples: Some of you are coming tonight. Some of the pie is nice. Any of them are able to excavate. None of it is enough. None of them are happy.</p>
<p>“and also when to use who vs whom?”</p>
<p>If the pronoun is the subject of a verb, use “who.” Otherwise, use “whom.”</p>
<p>Examples:</p>
<p>Whom do I want to eat? (The “whom” is not doing anything; it’s the direct object of “to eat.”)</p>
<p>Who is responsible? (“who” is doing the action of “is.”)</p>
<p>Whom am I attacking? Whom am I calling? (“whom” is not attacking or calling.)</p>
<p>I don’t know who is responsible. (“who is responsible” is indeed a direct object, but within this object “who” is being using nominatively as the subject of “is responsible.”)</p>
<p>I will arrest whomever I see. (“whomever” is not performing any action.)</p>
<p>I will arrest whoever is guilty. (“whoever” is a subject for “is guilty.”)</p>
<p>Thanks silverturtle. That’s a good guide for quick review.</p>
<p>No problem.</p>
<p>Thank you.I am glad whom vs who is barely tested on the SAT…</p>
