     UNIT 12

   Change the singular words given in the exercises below into plural.

1  Examples:

   After -ch, -sh, -s, -ss, -x, -z and -zz, we add -es.

a  fax
b  mass
c  gas
d  wish
e  match

2  Examples:
   play→plays (vowel + y)
   spy3→spies (consonant + y→i + es)

a  journey
b  boy
c  fly
d  university
e  salary

3  Examples:

   -fe and -f often change to -ves when making the plural. However, the following words do not undergo any change:

   At times, both combinations are possible, though:
     dwarf→dwarfs or dwarves
     handkerchief→handkerchiefs or handkerchieves
     hoof→hoofs or hooves
     scarf→scarfs or sacarves
     turf→turfs or turves
     wharf→wharfs or wharves

a  life
b  self
c  roof
d  turf
e  safe

4  Examples:
("kilo" is an abbreviation for "kilogramme".)
   concerto→concertos (The origin of this word is Italian, that is, foreign. "Concerti" is also possible, but less usual.)
   folio→folios (The -o is preceded by a vowel.)

   The -o ending makes the plural by adding -es. Yet, it only takes an -s with abbreviations and words whose origin is foreign4: bistro, casino, canto, curio, concerto, dynamo, hello (also hallo or hullo), hippo, inferno, kilo, kimono, photo, piano, pro, rhino, solo, soprano, torso and tremolo. Sometimes, both combinations are possible: banjo→banjos/banjoes; cargo→cargos/cargoes; commando→ commandos/commandoes; dodo→dodos/dodoes; fiasco→fiascos/fiascoes; flamingo→flamingos/flamingoes; ghetto→ghettos/ghettoes; innuendo→innuendos/innuendoes; halo→halos/haloes; lasso→lassos/lassoes; mango→mangos/mangoes; motto→mottos/mottoes; placebo→placebos/placeboes; tornado→tornados/tornadoes; veto→vetos/vetoes; volcano→volcanos/volcanoes. We add only one -s to the singular noun if the o is preceded by another vowel: kangaroo→kangaroos.

a  hero
b  tomato
c  photo
d  bamboo
e  canto

5  Example:

   "Skull" has a different ending from those given in the sections above, so we form the plural with an -s.

a  row
b  sword
c  navel
d  oven
e  ornament

6  Revision exercise.

t  burglar alarm5
u  brother-in-law
v  trip
w  dwarf
x  inferno
y  prey
z  dent

7  Example:

   Words of Greek origin ending in -is, form the plural by changing the -i- into -e-, as in the above example. Nevertheless, there are a few exceptions: chrysalis→chrysalises, chrysalides; iris→irises; metropolis→metropolises. Axis→axes, pelvis→pelvises, penis→penises (or penes) and testis→testes come from Latin.

a  diagnosis
b  oasis
c  thesis
d  axis
e  metamorphosis

8  Example:
(The Latin language took it from Greek.)

   Some Latin-origin substantives ending in -ex or -ix have two plural forms: one regular and one irregular, as seen above. Occasionally, we might have a variation in meaning. For example, appendix can refer to a book (appendices) and to a body (appendixes, appendices). The noun "mix" is not regarded as foreign by speakers of English; therefore, only the regular plural form is possible: mixes.

1  Busses is possible as well, especially in American English.
2  Note that the consonant is doubled too.
3  Notice the following: chilli→chillies (chili→chilies is American.)
4  Although "potato" is taken from the Castilian word "patata" —a blend from the Taino forms "papa" and "batata"—, it should be considered as an English one, because it has wholly adapted to the language.
5  Compounds generally make plural the last element. All the same, if we have an adjective in the second element, only the first element is made plural: court-martial→courts-martial.

   Phrasal verbs may become nouns. In this case, we add an -s to the end (break-up→break-ups, lay-by→lay-bys, turn-off→turn-offs, shake-out→shake-outs):
     She broke up with him.
     Their break-up caused him a lot of pain.

   However, exceptions can occur: passer-by→passers-by. Note too sister-in-law→sisters-in-law. Sister-in-laws is also possible in informal British English.

   When the words man or woman are in the compound, both nouns take the plural form: woman priest→women priests. If they are written as one word, and man or woman come first in the compound, they usually behave as ordinary nouns: manservant→manservants (also menservants), manhunt→manhunts, manhour→manhours; but statesman→ statesmen, sportswoman→sportswomen, handyman→handymen.
6  The plural of this word is regular. This noun was taken from French. It originally comes from Latin.
7  It is a blend: teleprinter + exchange. It has a regular plural.
8  In very formal contexts, "persons" is possible.
9  Words like buffalo, carp, crab usually make the plural with an -s, but no -s is added when they are used in specialized contexts. For instance, a hunter would say I killed two buffalo yesterday, but some Sunday trippers would say We saw a lot of buffaloes this morning.
