Adding Suffixes
Formation of derivative words with the help of suffixes and main rules for adding suffixes are described in this material. It is necessary to stress that language learners should not try to create new words by adding suffixes, even if you know how to do it. Use only those English words which already exist and are listed in dictionaries.
Suffixes with similar spelling and pronunciation (ance, ence, ant, ent, er, or, able, ible, ize, ise), together with recommendations for choosing suffixes, are described in Difficult Suffixes of Nouns and Adjectives and Difficult Suffixes of Verbs in the section Writing.
Derivation
Derivation is the formation of derivative words by adding derivational affixes (prefixes, suffixes) to existing words. For example: school – preschool; stardard – nonstandard; polite – politeness; beauty – beautiful; simple – simplify; kind – kindly. Some prefixes and suffixes are still productive; that is, they are still used to form new words. But many of them are no longer used in the formation of new words.
The addition of a derivational suffix usually (though not always) creates the word belonging to another part of speech, and the lexical meaning of the resulting word is always changed: memory – to memorize; kind – kindness. The addition of a prefix rarely changes the word's belonging to a certain part of speech: search – research; night – midnight.
Derivation by means of adding derivational suffixes is the most common type of word formation. Examples of typical patterns of derivation by means of suffixation are given below. Not all of the suffixes are used in the examples, and of course, not all nouns, adjectives, verbs and adverbs form derivatives in these ways.
Typical patterns of derivation
Nouns are formed from verbs by adding the suffixes AGE, AL, ANCE, ENCE, ER, OR, ION, MENT, Y: passage, arrival, appearance, existence, worker, editor, collection, agreement, inquiry.
Nouns are formed from adjectives by adding the suffixes ANCE, ENCE, NESS, TH, TY: elegance, intelligence, darkness, warmth, safety.
Nouns are formed from nouns by adding the suffixes ARY, ERY, ORY, DOM, HOOD, IAN, IST, ISM, SHIP: dictionary, slavery, territory, kingdom, childhood, musician, artist, capitalism, friendship.
Verbs are formed from nouns and adjectives by adding the suffixes ATE, EN, IZE, FY: activate, deepen, apologize, classtify.
Adjectives are formed from verbs by adding the suffixes ABLE, IBLE, ANT, ENT, ORY, IVE: reliable, convertible, ignorant, confident, contradictory, attractive.
Adjectives are formed from nouns by adding the suffixes ABLE, IBLE, AL, AN, IAN, ARY, ORY, EN, FUL, IC, ISH, LESS, OUS, Y: reasonable, sensible, cultural, American, humanitarian, legendary, compulsory, golden, beautiful, patriotic, foolish, hopeless, famous, windy.
Adjectives are formed from adjectives by adding the suffixes AL, ISH: poetical, greenish.
Adverbs are formed from adjectives by adding the suffix LY: exactly, logically.
Note: Inflection
Inflection (inflexion) is the modification of a word with the help of inflectional affixes (usually, with the help of inflectional suffixes, for example, the endings S, ED, ING) to form grammatical forms (plural forms, tense forms) of the same word. Main types of inflection are the following: declension of nouns and pronouns (a play – two plays; he – him); conjugation of verbs (to play – he plays, he is playing, he played); and comparison of adjectives and adverbs (early, earlier, earliest).
Main rules for adding S, ED, ING are described in Adding the Ending s/es to Nouns and Verbs and Adding the Endings ed, ing to Verbs in the section Writing. Main rules for adding ER, EST to adjectives and adverbs are described in Degrees of Comparison in the section Miscellany.
Zero derivation
Derivative words may also be formed from existing words without adding any prefix or suffix; that is, by using one and the same form of a word as another part of speech: to change – a change; dry (adj.) – to dry; early (adj.) – early (adv.). Zero derivation (conversion) is widely used in the formation of nouns from verbs and verbs from nouns.
Here's a short list of common words that can be used as nouns or verbs, with the same spelling and pronunciation: act, answer, book, break, call, change, deal, drink, face, fear, hand, head, help, light, look, love, mark, move, need, notice, order, pack, place, question, reply, ride, space, stay, telephone, time, walk, work.
Zero derivation may be accompanied by changes in pronunciation and spelling: use [yu:z] (v.) – use [yu:s] (n.); advise (v.) – advice (n.); respond (v.) – response (n.); believe [bi'li:v] (v.) – belief [bi'li:f] (n.); food (n.) – feed (v.). Nouns and verbs may also be formed in this way by shifting stress: import [im'po:rt] (v.) – import ['impo:rt] (n.); progress ['progres] (n.) – progress [prə'gres] (v.). Stress in derivative words is described in Word Stress in the section Phonetics.
Other types of word formation
Compounding is the formation of compound words by combining two or more existing words: highway, love story, old-fashioned, twenty-three. Examples of compound nouns, verbs, adjectives and numerals are provided in Stress in Compound Words in the section Phonetics.
Words are also borrowed from other languages. In the course of its history, English borrowed a large number of words from Latin, Greek, French, and from the Scandinavian languages. There are also some borrowings from other languages. For example, here are some loan words from Russian: babushka, balalaika, borscht, cosmonaut, dacha, ruble, rouble, samovar, sputnik, steppe, taiga, troika, tundra, tsar, vodka.
Creating completely new words (neologisms) is an ongoing process nowadays. New devices and new words for them appear, for example, cell phone, mobile phone, smart phone. The Internet seems to be an inexhaustible source of new words. Such recent neologisms as "blog, blogger, blogosphere, download, e-mail, login, online, spam, spammer, upload, website" have become quite common in our speech.
Usefulness of studying suffixes
Suffixes help us to recognize the part of speech to which some word belongs, and that helps us to understand the meaning of the word. For example, clearly recognizable suffixes of nouns, adjectives and verbs are the following:
Suffixes of nouns: AGE (courage), ANCE (assistance), ENCE (violence), ANCY (vacancy), ENCY (currency), ER (teacher), OR (visitor), DOM (freedom), HOOD (brotherhood), ICS (economics), IST (dentist), ISM (idealism), ION (region), TION (information), MENT (payment), NESS (business), SHIP (leadership), ITY (ability).
Suffixes of adjectives: ABLE (valuable), IBLE (flexible), FUL (useful), LESS (homeless), OUS (dangerous).
Suffixes of verbs: IZE (organize), ISE (advertise), IFY (simplify).
Meanings of suffixes
Knowing the meaning of suffixes helps us to understand the meaning of various words. Suffixes have general meanings. For example:
Noun suffixes ANCE, ENCE, ANCY, ANCY, DOM, HOOD, ION (TION), ISM, NESS, MENT, SHIP, Y denote state or act of what is indicated by the root of the word: absence, freedom, illness, citizenship, accusation, movement, delivery.
Noun suffixes ER, OR, EER, IST often denote a person performing an action or a person's profession: buyer, professor, engineer, pianist.
Adjectival suffixes ABLE, IBLE, ARY, ORY, FUL, IC, ISH, IVE, LESS, OUS denote features, qualities or properties of someone or something: preferable, invisible, legendary, obligatory, respectful, automatic, reddish, responsive, aimless, nervous.
Verb suffixes ATE, EN, IZE, FY mean "to perform the act of, to make": confiscate, lengthen, modernize, clarify. The adverbial suffix LY indicates that the action is performed in a certain manner: slowly, seriously, periodically.
Of course, you need to know both the meaning of the root and the meaning of the suffix in order to understand the whole word correctly. But even if you don't know the meaning of the root, the suffix still helps to identify the part of speech to which this or that word belongs.
Difficulties in studying suffixes
In some cases, one and the same suffix (or its homonyms) is used in the formation of words belonging to different parts of speech. Such suffixes require special attention.
The suffixes AL, ANT, ENT, ARY, ORY, IC, Y are used in the formation of nouns and adjectives: approval (n.), formal (adj.); lieutenant (n.), important (adj.); president (n.), confident (adj.); secretary (n.), necessary (adj.); laboratory (n.), preparatory (adj.); music (n.), basic (adj.); melody (n.), greedy (adj.).
The suffix ATE is used in the formation of adjectives, nouns and verbs: obstinate (adj.), doctorate (n.), calculate (v.). The suffix LY is used in the formation of adjectives and adverbs: lovely (adj.), nicely (adv.). The suffix EN is used in the formation of verbs and adjectives: widen (v.), wooden (adj.).
A word containing a suffix is often converted into a different part of speech by zero derivation, and then the suffix does not help us to understand to what part of speech this word belongs.
Suffixes that are often found in nouns and adjectives of the same form are AL (manual), AN (human), IAN (vegetarian), ANT (instant), IC (magic), IVE (detective). The suffix ATE is found in verbs, nouns and adjectives of the same form: graduate, moderate. The suffix LY is found in adjectives and adverbs of the same form: weekly, kindly.
To understand what parts of speech words with these suffixes represent, analyze them in sentences or in word combinations. For example, the word "graduate" in "he graduated from college in 2005" is a verb; the word "graduate" in "he is a Harvard graduate" is a noun; the word "graduate" in "a graduate student" is an adjective.
Changes in spelling and pronunciation that occur when suffixes are added present considerable difficulty for language learners. The material below should help you to sort out these issues.
Adding suffixes: General rules
Generally, when a suffix is added to a word ending in a consonant, the spelling of the word and the suffix are not changed.
adopt – adoption;
cold – coldness;
quick – quickly;
pass – passage;
act – active;
danger – dangerous.
Changes take place mostly in those cases where a suffix beginning with a vowel is added to a word ending in E or Y, and in some cases of adding to GE, CE, C, DE, D, T. Changes in pronunciation may also take place. Main cases of change in spelling and pronunciation are described below. Transcription is indicated according to American pronunciation.

Note: IC, ICAL
There are a lot of pairs of adjectives with the suffixes IC and ICAL (IC+AL). If the dictionary indicates the same meaning for the adjectives in the pair, the first variant is usually the most common. Some of such adjectives are different in meaning. For example:
history – historic – historical;
economy – economic – economical.
Adverbs add LY to ICAL
Adverbs are formed from such adjectives by adding the suffix LY only to the suffix ICAL (even if such adjectives with the suffix ICAL do not exist).
historic (adj.), historical (adj.) – historically (adv.);
ironic (adj.), ironical (adj.) – ironically (adv.);
basic (adj.) – basically (adv.).
BUT: public (adj.) – publicly (adv.).

Adding ER: ban, banner; cut, cutter; dig, digger; rob, robber; rub, rubber; tip, tipper.
Other examples: stop, stoppage; drop, droppable; fun, funny; red, reddish; sad, sadden.
Adding to final R: refer, referral; occur, occurrence; stir, stirring.
BUT: prefer, preferable; refer, reference.
Adding to final L: excel, excellent; cancel, cancellation; (BrE) travel, traveller; (AmE) travel, traveler.
Adding LY to final L always gives double L in the adverb: awful, awfully; gradual, gradually; normal, normally; official, officially; real, really.
