Word formation
1 Compounds
A Compound nouns
A compound noun can be formed by joining two nouns together,
e.g. hand + bag = handbag.
a handbag
the weekend
We stress the first part of the word: a ‘handbag.
football a guidebook my bedroom
There is little difference between a compound noun and two separate nouns
used one after the other, e.g. a phone bill. Some combinations can be written
either as a compound or as two separate nouns, e.g. guidebook or guide book.
Some compound nouns are formed from an adjective + noun or from a
verb + noun.
a greenhouse a blackboard
some workmen a searchlight
NOTE
Compare these phrases.
Compound noun: a ‘hotplate (= a place on a cooker where you heat food)
Adjective + noun: a hot ‘plate (= a plate which is hot)
B Gerund + noun
the dining-room (= the room for dining in)
We can use a gerund to classify a noun, to say what type it is or what its
purpose is.
a washing-machine (= a machine that washes clothes)
a sailing-ship some writing-paper a swimming-pool
We often use a hyphen after the gerund. We stress the gerund, e.g. the
‘dining-room.
the booking office
NOTE
Compare a gerund and a participle.
Gerund: a ‘sleeping-pill (= a pill that helps you to sleep)
Participle: a sleeping ‘child (= a child who is sleeping)
C Noun + gerund
We can form a compound with a noun + gerund.
Taxi-driving was what I ended up doing.
We had three days of sightseeing.
Coin-collecting is an interesting hobby.
We stress the noun, e.g. ‘coin collecting.
The noun in this pattern is singular, e.g coin-collecting. But after a gerund the noun
can be either singular or plural depending on the meaning.

Driving a taxi was what I ended up doing.
Collecting coins is an interesting hobby.
D Compound modifiers
We can use a number + noun to modify another noun.
a three-day visit a sixty-mile journey a car with four-wheel drive
The noun in this pattern is usually singular, e.g. a three-day visit.
The modifier can also be a number + noun + adjective.
a three-day-old baby a hundred-metre-long queue
We can also form compounds with participles.
a road-widening scheme a hard-boiled egg
2 Prefixes
A A prefix is something that we can put at the beginning of a word to change the
meaning. Compare these two sentences.
I calculated the amount I would need.
I miscalculated the amount I would need.
(= I wrongly calculated the amount I would need.)
Here the prefix mis- (= wrongly) changes the meaning.
B Here are some prefixes and some examples of words we can form with them.

We do not use in- before b, l, m, p, or r. We use il-, im-, and ir- instead.
3 Suffixes
A Introduction
A suffix comes at the end of a word. For example, we can add the suffix –ness
to the adjective kind to form the noun kindness. Compare these two
sentences.
We won’t forget how kind you’ve been.
We won’t forget your kindness.
Here the use of the suffix to form a noun makes the sentence shorter
and neater.
Sometimes the addition of a suffix involves other changes in the form or
pronunciation of the word.
apply ➔ application
possible ➔ possibility
courage /ˈkʌrɪdʒ/ ➔ courageous /kəˈreɪdʒəs/
Copyright Oxford University Press

Changes in pronunciation can involve both sounds and stress. For example,
when we add –ous to courage, the stress changes from the first to the second
syllable.
TIP
Not all combinations of words and suffixes are possible. For example, we
can add –ment to some verbs to form statement, amusement, punishment,
and so on. But we cannot add –ment to every verb. The possible
combinations have to be learned as individual words.
B Abstract nouns
Here are some ways that we can add a suffix to a verb or adjective to form a
noun – usually an abstract noun.
Verb ➔ noun ending in -ion
Verb + -ment
Verb + -ance/-ence
Verb + -ing
Adjective + -ness
Adjective in –ant/–ent
➔ noun in –ance/-ence
Adjective + -ty/-ity
correct ➔ correction,
discuss ➔ discussion
produce ➔ production,
describe ➔ description
inform ➔ information,
invite ➔ invitation
add ➔ addition,
repeat ➔ repetition
decide ➔ decision,
permit ➔ permission
development, government,
movement, payment
acceptance, performance;
existence, preference
a building, my feelings
blindness, forgetfulness, illness,
sadness
distant ➔ distance,
important ➔ importance
absent ➔ absence,
silent ➔ silence,
violent ➔ violence
certainty, royalty; nationality,
stupidity
C Driver, student, tourist, etc.
There are a number of endings that we use to express a person’s role.
Noun/Verb + -er/-or
Noun/Verb/Adjective + -ist
builder, driver, footballer, interviewer, lawyer, owner,
smoker, walker, writer > Note a
editor, navigator
journalist, motorist, nationalist, tourist
Copyright Oxford University Press
4
Verb + -ant/-ent
Verb + -ee
Noun + -an/-ian
NOTE
a
assistant, informant, inhabitant, servant
correspondent, student
addressee, employee, interviewee, payee
> Note b
republican; historian, musician > Note c
We also use –er in many nouns referring to a device such as a tool or machine,
e.g. a computer, a food mixer, a heater, a screwdriver.
b The suffix –ee usually has a passive meaning. Compare –er and –ee.
The company is the biggest employer in the town. It has two thousand employees.
c Some adjectives of nationality end in –an/-ian, e.g. American, Brazilian. > 6B
D Friend, waitress, policeman/policewoman, etc
Most nouns for people can mean either a male or a female, so a friend, a student, a
doctor, a motorist, etc. can be either a man or a woman.
My friend has sold his car. (a male friend)
My friend has sold her car. (a female friend)
If we need to specify what sex, we add another word, e.g. her boyfriend, female
students, women doctors.
Some words for family members are different for males and females, e.g. husband/
wife, father/mother, son/daughter, brother/sister, uncle/aunt. But a cousin can be
male or female.
We can add the female suffix –ess to some nouns. A prince is male, and a princess is
female. Other examples are hostess and empress. But be careful not to over-use –ess.
Where there is a word that can refer to either sex, e.g. manager or poet, it is old-
fashioned and may be seen as sexist to use manageress or poetess. The only jobs
where –ess is still regularly used are actress and waitress, although actor can refer to
either a man or a woman.
There is also a male suffix -man /mən/ and a female suffix –woman, e.g.
businessman/businesswoman, chairman/chairwoman, policeman/policewoman,
salesman/saleswoman, spokesman/spokeswoman. But these are now often
regarded as sexist, and words that can refer to both males and females are
preferred. Sometimes we use the suffix –person, e.g. the chairperson, a salesperson.
Or we use a different word, e.g. a business executive, a police officer, a sales
representative.
NOTE
Some adjectives of nationality end in –man/-woman, e.g. Frenchman, Irishwoman. > 6B
E Verbs
There are many verbs in –ize formed from adjectives with an abstract meaning.
We can also add –en to some adjectives with a concrete meaning.

Adjective + -ize
Adjective + -en
centralize, legalize, modernize, popularize, privatize
brighten, harden, loosen, sharpen, shorten, widen
NOTE
a The ending –ize can also be spelled –ise in British English: centralize/centralise.
b Some adjectives can be used as verbs, e.g. clear, empty.
F Adjectives
Noun + -al
Noun + -ic
Noun + -ful
Noun + -less
Noun + -ous
Noun + -y
Noun + -ly
Verb + -ive
Verb + -ing
Verb + -ed
Verb + -able/-ible
and carefully.
industrial, national, natural, original, traditional
artistic, energetic, heroic, photographic
careful, hopeful, peaceful, powerful, wonderful > Note a-b
careless, hopeless, powerless, useless, worthless > Note b

NOTE
a Nouns with the suffix –ful end in a single l, but the adverb has two. Compare careful
b -less is a negative suffix. Hopeless means ‘without hope’. Painful and painless
are opposites.
c Hourly, daily, weekly, and monthly can be adjectives or adverbs.
d The suffix –able/-ible often means that something can be done.
This sweater is washable. (= This sweater can be washed.)
But not all adjectives in –able/-ible have this meaning, e.g. pleasurable (= giving pleasure),
valuable (= worth a lot), formed from the nouns pleasure and value.
G Adverbs
Many adverbs are formed from an adjective + -ly, e.g. quick ➔ quickly.
4 Vowel and consonant changes
A Sometimes two related words have a different vowel sound.
We could feel the hot sun on our backs.
We could feel the heat of the sun on our backs.
Here hot is an adjective, and heat is a noun.
Other examples are blood ➔ bleed, food ➔ feed, full ➔ fill, lose ➔ loss,
proud ➔ pride, sell ➔ sale, shoot ➔ shot, sing ➔ song, sit ➔ seat.

B Two related words can have a different consonant sound.
The explanation was hard to believe.
The explanation was beyond belief.
Here believe is a verb, and belief is a noun.

speak ➔ speech.
C
Sometimes there is more than one sound change, e.g. choose ➔ choice,
lend ➔ loan, live /lɪv/ ➔ life /laɪf/, succeed ➔ success, think ➔ thought.

stressed.
