Word Formation: English ЕГЭ 2025 Preparation

Word formation is the process of creating new words from existing ones. Understanding the principles of word formation is essential for the ЕГЭ English exam, as it helps expand your vocabulary and improve your ability to comprehend and use English words correctly. This guide will help you master the main word formation processes in English.

Theory for Exam Preparation

In English, new words can be formed through various processes, including affixation (adding prefixes and suffixes), compounding (combining two or more words), conversion (changing a word's part of speech without changing its form), and other methods. Mastering these processes will help you recognize and create new words, which is crucial for achieving a high score in the ЕГЭ English exam, particularly in the vocabulary and reading comprehension sections.

Affixation

Affixation is the process of adding affixes (prefixes or suffixes) to a base word to create a new word with a different meaning or function.

Prefixes

Prefixes are added to the beginning of a word to modify its meaning. Here are some common prefixes in English:

PrefixMeaningExamples
un- not, opposite of unhappy, unable, unfair
dis- not, opposite of disagree, dislike, dishonest
in-, im-, il-, ir- not, opposite of inactive, impossible, illegal, irregular
re- again, back rewrite, return, rebuild
pre- before prehistoric, preview, prepay
post- after postwar, postgraduate, postpone
anti- against, opposing antiwar, antisocial, antibacterial
auto- self autobiography, automatic, autopilot
bi- two bilingual, bicycle, biannual
co- together, with cooperate, coexist, coauthor
de- remove, reduce deactivate, defrost, devalue
ex- former ex-husband, ex-president, ex-employee
inter- between international, interact, interchange
mid- middle midday, midnight, mid-October
mis- wrongly misunderstand, misinform, misplace
multi- many multicultural, multimedia, multilingual
non- not nonsense, non-smoking, non-fiction
over- too much overeat, overwork, overreact
semi- half semicircle, semifinal, semi-detached
sub- under submarine, subway, subconscious
super- above, beyond superhuman, supermarket, supernatural
trans- across, beyond transport, translate, transform
under- too little, beneath underestimate, underground, underweight
Note!

The choice of the negative prefix (un-, dis-, in-, etc.) often depends on the origin of the word:

- Words of Germanic origin often take un- (unhappy, unable)

- Words of Latin origin often take in- (inactive, invisible)

- The prefix in- changes to im- before words beginning with b, m, or p (impossible, immature, impatient)

- The prefix in- changes to il- before words beginning with l (illegal, illegible)

- The prefix in- changes to ir- before words beginning with r (irregular, irresponsible)

Suffixes

Suffixes are added to the end of a word to change its part of speech or modify its meaning. Here are some common suffixes in English:

When adding suffixes, the spelling of the base word sometimes changes: happy + -ness = happiness (no change) happy + -ly = happily (y changes to i) care + -ful = careful (no change) hope + -ing = hoping (final e is dropped) run + -ing = running (final consonant is doubled)

Compounding

Compounding is the process of joining two or more words to create a new word with a meaning that is often different from the meanings of its components.

Types of Compounds

Based on Parts of Speech

TypeStructureExamples
Compound Nouns noun + noun
adjective + noun
verb + noun
verb + adverb
preposition + noun
bedroom, blackboard, washing machine, breakdown, underground

Note!

The form of a compound (closed, hyphenated, or open) is not always predictable and may vary between different varieties of English. When in doubt, consult a dictionary.

Conversion

Conversion, also known as zero derivation, is the process of changing a word's part of speech without changing its form.

Conversion TypeExamples

Common Spelling Changes in Word Formation

When adding affixes, the spelling of the base word sometimes changes:

RuleExamples
Dropping final 'e' hope + -ing = hoping
write + -ing = writing
love + -able = lovable
Keeping final 'e' change + -able = changeable
courage + -ous = courageous
notice + -able = noticeable
Doubling final consonant run + -ing = running

Changing 'y' to 'i' happy + -ness = happiness
beauty + -ful = beautiful
easy + -ly = easily
Keeping 'y' play + -er = player
enjoy + -able = enjoyable
boy + -ish = boyish
Rules for Doubling the Final Consonant:

The final consonant is doubled when:

1. The word has one syllable (stop → stopped)

2. The word has more than one syllable and the stress is on the final syllable (begin → beginning)

3. The word ends in a single consonant preceded by a single vowel (run → running)

The final consonant is NOT doubled when:

1. The word has more than one syllable and the stress is not on the final syllable (visit → visited)

2. The word ends in more than one consonant (help → helped)

3. The word ends in a consonant preceded by more than one vowel (rain → raining)

Key Points to Remember

Exam Tip!

In the ЕГЭ English exam, word formation tasks often require you to change a given word into a different part of speech to fit a sentence. Pay attention to the context to determine whether you need a noun, verb, adjective, or adverb. Also, be careful with spelling changes when adding affixes, and remember that some words may require both a prefix and a suffix (e.g., "unhappiness" from "happy").
