6 Noun Phrases
/k/ back-backs; leak-leaks; trick-tricks; bike-bikes; lake-lakes
/f/ cliff-cliffs; cough-coughs; laugh-laughs; cuff-cuffs; sniff-sniffs
/θ/ path-paths; lath-laths; monolith-monoliths, bath-baths
2. If the noun ends in a voiced consonant sound (except a sibilant) or any vowel (all vowels
in English are voiced), then the plural is formed with the voiced sibilant /z/, which is also spelled
-s. Here are examples of all the consonant sounds that this rule applies to:
/b/ lab-labs; web-webs; blob-blobs; globe-globes; tube-tubes
/d/ bed-beds; fl uid-fl uids; fl ood-fl oods; code-codes; shade-shades
/g/ bug-bugs; rag-rags; fl ag-fl ags, pig-pigs; hog-hogs
/v/ wave-waves; hive-hives; love-loves; live-lives; cove-coves
/l/ girl-girls; pill-pills; wheel-wheels; role-roles; rule-rules
/m/ ham-hams; farm-farms; room-rooms; fl ame-fl ames; home-homes
/n/ hen-hens; teen-teens; moon-moons; loan-loans; tune-tunes; throne-thrones
/ŋ/ ring-rings; thing-things; throng-throngs; rung-rungs; song-songs
Since all vowels are voiced in English, this rule also governs the plural of all words ending in
a vowel sound. For example:
sea-seas; zoo-zoos; cow-cows; bee-bees; show-shows; tree-trees
Words ending in the letter y are little more complicated. When the singular form of a word
ends in a consonant ϩ the letter y (that is, when the letter y represents a vowel sound), we form the
regular plural by changing the y to i and adding -es. (There is a schoolroom saying that goes like
this: “Change the y to i and add -es.”)
The plural -s is pronounced /z/ in the expected way. The change of y to ie does not affect pro-
nunciation—it is a graphic change only. Here are some examples (all with a /z/ pronunciation):
Singular Plural
baby babies
family families
lady ladies
sky skies
story stories
When the letter y is combined with a vowel, a different spelling rule applies. To see the differ-

ence, compare the spellings of the plurals of the words fl y and toy:

Nouns 7
Singular Plural
fl y fl ies
toy toys
In the word fl y, the y by itself represents a vowel sound. That is why the spelling rule that changes
the y to i states that the y must be preceded by a consonant—this is just a way of ensuring that we
are talking about y used by itself to represent a vowel sound.
In the word toy, the vowel sound is represented by a combination of the two letters o ϩ y, which
is sometimes called a blend. Think of the oy spelling as a fi xed unit that cannot be changed. To
form its plural we merely add an s (pronounced /z/) as we would with any other vowel spelling.
Combinations of other vowels with y follow the same rule. Here are some more examples of oy, ey,
and ay plural spellings:
Singular Plural
boy boys
key keys
subway subways
tray trays
Exercise 1.2
All of the nouns in the following list form their plural in the regular way with a single sibilant
sound spelled -s. Depending on the nature of the fi nal sound in the singular form of the noun,
the -s can be pronounced either /s/ or /z/. Write the entire plural form of the noun in the /s/ or
/z/ column that shows the pronunciation of the plural -s. (Hint: Say the words out loud. If you
whisper or say them to yourself, voiced sounds will be automatically de-voiced so they will sound
the same as voiceless sounds.)

3. If the noun ends in a sibilant sound, either voiceless or voiced, then the plural is pro-
nounced as a separate unstressed syllable /ǝz/ rhyming with “buzz,” spelled -es. (Of course, if
the singular already ends in a silent e, we would add just an -s as in horse-horses, or else we would
have crazy spellings like X horse-es.) Here are examples of the most common consonant sounds
that this rule applies to:
/s/ (often spelled -ce) glass-glasses; bus-buses; face-faces; prince-princes; rinse-rinses;
fox-foxes
/š/ (often spelled -sh) wish-wishes; rash-rashes; McIntosh-McIntoshes; bush-bushes
/č/ (spelled -ch or -tch) watch-watches; switch-switches; bunch-bunches
/ǰ/ (spelled -ge or -dge) rage-rages; page-pages; dodge-dodges

/z/ buzz-buzzes; phase-phases; blaze-blazes; nose-noses; cruise-cruises
Exercise 1.3
All of the nouns in the following list form their plural in the regular way with a single sibilant

voiceless sounds.)

way.

10 Noun Phrases
Seven words form their plural by a vowel change alone:
Singular Plural
foot feet*
goose geese
louse lice
man men
mouse mice
tooth teeth
woman women**
Notes: *In addition to the usual plural form feet, the noun foot has a second plural form foot
when we use the word to refer to length or measurement. For example:
I bought a six foot ladder.
He is six foot three inches tall.
**Despite the spelling of women, it is the pronunciation of the fi rst syllable rather than the second
that changes: woman is pronounced /wo mǝn/; women is pronounced /w
I mǝn/; the second syl-
lables, -man and -men, are pronounced exactly alike with an unstressed vowel /mǝn/.
Two words retain an old plural ending, -en:
Singular Plural
ox oxen
child children
The long vowel in the singular child also changes to a short vowel in the fi rst syllable of the plural

children.
Some words ending in f form their plurals by changing the f to v and adding -es. Here are the
most common words that follow this pattern:
Singular Plural
half halves
knife knives
leaf leaves
life lives
loaf loaves
self selves

wolf wolves
Some words have a plural form that is identical to their singular form. Most of these words
refer to animals or fi sh. For example:
Singular Plural
a cod two cod
a deer two deer
a fi sh two fi sh
a sheep two sheep
a shrimp two shrimp
a trout two trout
Since the singular and plural forms of these nouns are identical, the actual number of the
noun can only be determined by subject-verb agreement or by the use of an indefi nite article. For
example:
Singular: The deer was standing in the middle of the road.
Plural: The deer were moving across the fi eld.
Singular: I saw a deer in the backyard.
Plural: I saw some deer in the backyard.

If one of these words is used as an object with a defi nite article, then the number is ambiguous.
For example:
Look at the deer! (one deer or many deer?)
Exercise 1.4
The following sentences contain one or more incorrect irregular plurals. Draw a line through
each incorrect plural and write the correct form above it.

I sliced the loafs and put the knifes back in the drawer.

2. Like all farmers, she has a constant problem with mouses and rats.

Noncount nouns
The types of noncount nouns that you are most likely to encounter fall into the semantic catego-
ries listed below:
Abstractions: beauty, charity, faith, hope, knowledge, justice, luck, reliability
Food: butter, cheese, chicken, pepper, rice, salt
Liquids and gases: beer, blood, coffee, gasoline, water, air, oxygen
Materials: cement, glass, gold, paper, plastic, silk, wood, wool
Natural phenomena: electricity, gravity, matter, space
Weather words: fog, pollution, rain, snow, wind
With certain exceptions that are discussed below, these noncount nouns are ungrammatical

if they are used in the plural. For example:
X Please get some more butters.
X We need to stop and get gasolines.
X The cements on the garage fl oors are cracking.
X The electricities have been turned off in all the apartments.
X Everyone has noticed the worsening pollutions around major cities.
Many noncount nouns can be used as count nouns with a predictable shift in meaning to some-
thing like “different kinds of.” Here are some examples:
gasoline (noncount): The price of gasoline is outrageous. (liquid)
gasoline (count): The station sells three gasolines. (different kinds or grades of
gasoline)
