a clinics. For a regular plural, just add s.
b nuthouses. Regular plural here: Add an s.
c thatches. For a noun ending in ch, add es.
d sexes. To a noun ending in x, add es to form a plural.
e graphs. Did I fool you? The h at the end of the noun doesn’t, all by itself, call for es. Only words
ending in sh or ch require an added es in the plural form. For graph, a plain s will do.
f turkeys. For nouns ending in ay, ey, and oy, add s to form a plural.
g women, lashes. The plural of woman is irregular. The second noun ends in sh, so you must tack
on es for a plural.
h sighs. Regular plurals are fun; just add s.
i belfries. The plural of a noun ending in consonant-y is created by dropping the y and adding ies.
j deer, squirrels, geese. The first and third nouns form irregular plurals, but good old squirrels
follows the rule in which you simply add s to the singular.
k is, wriggles. You need two singular forms here: blue is and Nadine wriggles.
l has, suffers. The verbs has and suffers are singular, as they should be, because the subject-verb
pairs are hair has and he suffers.
m are. The plural verb are matches the plural subject we.
n believe, give. The pronoun you always takes a plural verb such as believe and give.
o Do, tell. Both verbs are plural, matching the plural subjects you and friends. In the first pair, the
subject is tucked between the two parts of the verb because the sentence is a question.
p Has. You need a singular form here to pair with the singular subject his story.
q knows, is. Both answers are singular and match the singular subjects no one and John.
r has. Because he is singular, the verb has must also be singular.
s does. The pronoun everyone is singular, so it matches the singular form does.
t was. The singular verb was matches the singular subject I.
u were. The subject is guards; there is never a subject. Guards is plural and takes the plural
verb were.
v was. Ignore the interrupters (as well as . . . Alissa) and zero in on the real subject David. Match
the singular verb was to the singular subject.
