Agreement Flashcards
25 Most Prevalent Perplexities and Controversies (from Einsohn)
Name the 3 principles of subject-verb agreement.
-
formal (or grammatical) agreement
a singular subject requires a singular verb; a plural subject requires a plural verb -
notional concord
when number of subject is uncertain or when overt grammatical form conflicts w/ intended meaning, we rely on the verb that matches the meaning, not the overt grammatical form.
Fifty pages of manuscript is a day’s worth of work. -
attraction (or proximity)
verb takes the form of the closest subject
For those who attended the second day of the annual meeting, there was an early morning panel and afternoon workshops.
What is the elementary principle of subject-verb agreement?
The grammatical subject determines the number of the verb.
Thus
Nouns that appear in the predicate have no bearing on the number of the main verb
The only SIGN of Christmas WAS the stocking on the mantel
The only sign of Christmas (was, were) the stocking on the mantel.
WAS
- Only the grammatical subject determines the number of the verb.
- Nouns that appear in the predicate have no bearing on the number of the main verb
A pair of singular nouns joined by AND requires a (singular, plural) verb.
What are the two exceptions?
PLURAL
- appositive nouns joined by AND
- Nouns joined by AND that form a collective idea or unitary whole.

IS
Rule: Nouns joined by and to form a COLLECTIVE IDEA or UNITARY WHOLE are singular.
Consumer and business confidence (remains, remain) high.
REMAIN
Remain is plural even though confidence is singular, because of the ELLIPTICAL CONSTRUCTION of the compound subject, i.e., the subject is “consumer [confidence] and business confidence.” To use a singular verb would imply that there is an entity known as “consumer and business confidence.
For copyeditors, a style manual, as well as a dictionary, (is, are) useful.

Find and fix fault:
The governor described his health-care proposal to an enthusiastic crown. It was one of the best-attended campaign rallies of the year.
Fault: AWOL antecedent
“It” is meant to refer to “rally,” which is nowhere to be found in preceding sentence.

Or: The governor described…to an enthusiastic crown. The campaign rally was one of the best-attended campaign rallies of the year.
Smith is the candidate (who, whom) we think will win.

What are the three types of compounds?
open (think tank)
closed (jackknife)
hyphenated (mind-set)
homemade (i.e. no dictionary entry) compounds that are placed before a noun are known as——
How are they punctuated?
PREPOSITIVE
hyphenated
e.g., forward-thinking editors
Homemade/temporary (i.e., not in the dictionary) compounds that appear after the noun are referred to as——
How are they punctuated?
POSTPOSITIVE
They are left open (no hyphens)
e.g., editors who are forward thinking
compare to the prepositive
forward-thinking editors
Which is correct?
(a) A happily married spouse
(b) A happily-married spouse
(a) a happily married spouse
Rule: Compound adjectives composed of adverb ending in “ly” and an adjective or participle standing in for an adjective do not take a hyphen (pre- or postpositively)
Which is correct:
(a) a well-read woman
(b) a well read woman
(a) a well-read woman
Compound adjectives composed of an adverb that does not end in “-ly” and an adjective or participle standing in for an adjective always use a hyphen
Which is correct?
(a) a rather-awkward moment
(b) a rather awkward moment
(a) a rather-awkward moment
Compound adjectives composed of an adverb that does not end in “-ly” and an adjective or participle standing in for an adjective always use a hyphen
Which is correct:
(a) an extremely well-read woman
(b) an extremely well read woman
(b) an extremely well read woman
Per Chicago, when a hyphenated compound adjective is further modified by an adverb, the original compound hyphen is sometimes dropped to avoid possible misreading.
Which compound adjective is correct?
(a) pre-Industrial Revolution machinery
(b) pre-Industrial-Revolution machinery
(c) pre–Industrial Revolution machinery
(c) pre–Industrial Revolution machinery
Rule: Compound adjectives composed of compound nouns and prefixes or suffixes call for an EN DASH when used as modifiers (to avoid a lot of unsightly hyphens).
Which compound is correct?
(a) Academy-Award-winning actor
(b) Academy Award winning actor
(c) Academy Award–winning actor
(c) Academy Award–winning actor

Note: this does not just apply to proper nouns/adjectives.
Holding our nephew’s sweet-smelling, cuddly body made my husband and (I, me) realize that we wanted a child of our own.
ME
Use the objective case (me) as the subject of an infinitive. In this case, the infinitive is bare–that is, it does not include “to.” The way to read it is “…made us [to] realize…”
The compound subject might give writers trouble, so the easy way to figure out whether to use I or me is to substitute we or us.
He said that surgeries and therapy had helped him not only [to recover from his fall], but had also [freed him of the debilitating back pain].
Fault: Miscoordination
He said that surgeries and therapy had not only [helped him to recover from his fall], but also [freed him of the debilitating back pain].
- In this sentence the coordinates come in matched pairs, with a quantifier (both, either, neither, not only) marking the first coordinate and a coordinator (and, or, nor, but also) marking the second.*
- Rule: The phrases following coordinations much be PARALLEL.*
- In the original sentence, there’s an infinitive (to recover) in the first coordinate and a past participle (freed) in the second.*
- FIX: The easiest way to repair an unbalanced coordination is to zero in on the second coordinate and then force the first coordinate to match it by sliding its quantifier into a more suitable spot. [source: Pinker p.96]*
With Mr. Ruto’s appearance before the court, a process began that could influence not only [the future of Kenya] but also [of the much-criticized tribunal].
With Mr. Ruto’s appearance before the court, a process began that could influence the future not only [of Kenya] but also [of the much-criticized tribunal].
Fault: Miscoordination
Rule: The phrases following coordinations much be PARALLEL.
In this sentence the coordinates come in matched pairs, with a quantifier (both, either, neither, not only) marking the first coordinate and a coordinator (and, or, nor, but also) marking the second.
In the original sentence, we have a direct object (the future of Kenya) in the first coordinate and an oblique object (of the much criticized tribunal) in the second.
FIX: The easiest way to repair an unbalanced coordination is to zero in on the second coordinate and then force the first coordinate to match it by sliding its quantifier into a more suitable spot–rightward in this example. [source: Pinker p.97]
Ms. Popova, who died at 91 on July 8 in Moscow, was inspired both [by patriotism] and [a desire for revenge].
Ms. Popova, who died at 91 on July 8 in Moscow, was inspired by both [patriotism] and [a desire for revenge].
Fault: Miscoordination; mismatched objects (by patriotism and a desire for revenge)
Repair in either of two ways: by nudging not only rightward (thus: patriotism and a desire for revenge) or by suplyingthe second coordinate with a by to match the first one (by patriotism and by a desire for revenge)
I don’t remember the moment I first heard of “Mrs. Bridge”; it was one of those books that was in my house, and therefore my consciousness, when I was growing up.
The relative pronoun “that” refers to the plural “books,” not the singular “one.”
So make it “one of those books that WERE in my house.”
Or, simplify it: “one of the books in my house.”
It’s funny and also somewhat depressing, which pretty much sums up “The Room,” one of those cultish attractions that is so terrible it makes you wonder if the laugh finally is on us.
“…one of those cultish attractions that ARE so terrible THEY MAKE you wonder if…”
The relative pronoun “that” is plural in a “one of those” construction–it’s antecedent is “attractions.”
Missouri is one of several states that has had trouble procuring drugs for lethal injection, as manufacturers have declined to sell drugs to correctional facilities.
… one of several states that HAVE …
The relative clause describes “several states,” not just “one.”
After receiving his doctorate at Princeton, the university hired him as assistant professor and promoted him to full professor in 1965.
After he received his doctorate…the university…
Fault: Dangler
The introductory modifying phrase is a so-called dangler. In precise usage, “receiving” should apply to the noun (or pronoun) immediately following the modifying phrase. But here it doesn’t — the university did not receive a doctorate. One simple fix is to make the initial phrase a separate clause with its own subject “After he received …”
The only criteria is that the player played for five season, made one All-Pro team or pro bowl and has been retired for five full seasons.
“Criteria” is plural. Make it “The only criteria are … ”
The singular of “criteria” is “criterium.”
What is the key to avoiding errors of subject-verb agreement?
Knowing (1) how to pick out the subject for every verb and (2) how to tell whether that subject is singular or plural.
Compound subjects joined by and take a singular or plural verb?

When do compound subjects most frequently pose problems of agreement?
In an inverted sentence order, i.e. when the verb precedes the subject.
How important to your operation ARE your West Coast office and your Washington bureau?
TIP: Train yourself to check the subject-verb agreement whenever you use an inverted sentence order.
If you mentally put the subject before the verb, any mistake should become apparent.

ARE
When writers invert the normal order, putting the verb before the subject, they sometimes fail to prepare for a double subject.

ARE
[Does/Do] an orange and a grapefruit have the same number of calories?

There [is, are] a police officer at the front door and two reporters at the back.
ARE
Pay particular attention to INVERTED CLAUSES that begin with there and a singular verb form (there is/was/seems); make sure that the subject that follows doesn’t need a plural verb.
but, if grammar requires a form that sounds awkward, recast the sentence. For instance:
There are two reporters at the back door and a police officer at the front.
There [seems/seem] to be at least one factual error and several false assumptions in this report.
SEEM
Pay particular attention to INVERTED CLAUSES that begin with there and a singular verb form (there is/was/seems); make sure that the subject that follows doesn’t need a plural verb.
One crucially important linkage and desperately needed collegial contact [is, are] between community college teachers and the university faculty.
The compound subject arguably consists of two words designating one idea and so should take a singular verb, despite being joined by and.
The trial and conviction of Alger Hiss [is, are] becoming as much a cause celebre as the Sacco and Venzetti case.
IS
The compound subject arguably consists of two words designating one idea and so should take a singular verb, despite being joined by and.
but
Note that ideas can be closely related and yet distinct; any doubt on this issue should incline you toward a plural verb.
His education and background [gives, give] him an important advantage in dealing with academics.
GIVE
Note that ideas can be closely related and yet distinct; any doubt about whether a compound subject joined by and forms a single concept/idea should incline you toward a plural verb.
George Eliot understood how much resentment and suppressed rage there [was, were] in women.
WERE
Note that ideas can be closely related and yet distinct; any doubt about whether a compound subject joined by and forms a single concept/idea should incline you toward a plural verb. (Cook p78)
The strength of the dollar abroad, along with the rising costs of domestic resorts, have made European travel attractive to American vacationers.
Fault: subject-verb disagreement
HAS
When a singular noun is followed by a prepositional phrase like together with, along with, as well as, always use a singular verb.
Note: A preposition cannot substitute for the conjunction and, which alone can link words to form a compound subject. Plus, the object of a preposition cannot be the subject of a verb.
A coordinating conjunction like and joins sentence elements of equal grammatical weight; a preposition shows the subordinate relation its object bears to some other sentence element.
The senator, together with several advisers, are preparing a bill that would restrict a utility company’s right of eminent domain.
