Unit 7: Vocabulary and Usage - Subjective Questions

Word building is the process of forming new words from existing roots, stems, affixes, or other words.

It is important because it:

• Expands vocabulary: From act, we can form action, active, actor, and activity.
• Helps identify meaning: The prefix un- in unhappy indicates a negative meaning.
• Changes grammatical function: The noun beauty becomes the adjective beautiful.
• Improves accuracy in usage: Knowing the difference between decide and decision helps a learner select the correct form.

Common methods of word building include prefixation, suffixation, compounding, conversion, clipping, blending, and the formation of acronyms.

A prefix is a letter or group of letters added to the beginning of a root word. It normally changes the meaning of the word without necessarily changing its part of speech.

Examples:

• happy → unhappy: un- means not.
• write → rewrite: re- means again.
• possible → impossible: im- gives a negative meaning.
• agree → disagree: dis- means not or the opposite of.
• war → pre-war: pre- means before.
• national → international: inter- means between or among.

Thus, prefixes help create new words by adding ideas such as negation, repetition, time, degree, or position.

A suffix is a letter or group of letters added to the end of a root or stem. A suffix may change both the meaning and the grammatical class of a word.

Examples:

• teach (verb) + -er → teacher (noun)
• happy (adjective) + -ness → happiness (noun)
• beauty (noun) + -ful → beautiful (adjective)
• modern (adjective) + -ize → modernize (verb)
• quick (adjective) + -ly → quickly (adverb)

Therefore, suffixes are important in building nouns, verbs, adjectives, and adverbs from a common root.

• unhappiness = un- + happy + -ness
  • un- means not.
  • happy is the root.
  • -ness changes the adjective into a noun.
• disagreement = dis- + agree + -ment
  • dis- expresses opposition or negation.
  • agree is the root verb.
  • -ment forms a noun.
• rereading = re- + read + -ing
  • re- means again.
  • read is the root verb.
  • -ing forms a participle or gerund.
• careless = care + -less
  • care is the root noun or verb.
  • -less means without and forms an adjective.
• international = inter- + nation + -al
  • inter- means between or among.
  • nation is the root noun.
  • -al forms an adjective.

Nouns can be formed from verbs and adjectives by adding noun-forming suffixes.

Nouns formed from verbs:

• act + -ion → action
• develop + -ment → development
• perform + -ance → performance
• employ + -ee → employee
• teach + -er → teacher

Nouns formed from adjectives:

• kind + -ness → kindness
• pure + -ity → purity
• free + -dom → freedom
• long + -th → length
• wise + -dom → wisdom

Some formations involve spelling changes, such as decide → decision and strong → strength. The resulting nouns may name an action, state, quality, person, or result.

Verbs can be formed from nouns or adjectives by adding suffixes such as -ize, -ify, -en, and -ate.

Examples:

• modern → modernize
• beauty → beautify
• simple → simplify
• strength → strengthen
• wide → widen
• active → activate

Prefixes may also help form verbs, as in courage → encourage and danger → endanger.

Sentences:

• The new equipment will modernize the factory.
• Regular practice will strengthen your writing skills.

The suffix or prefix changes the base word into a verb expressing an action, process, or change of state.

1. Act

• act — noun or verb
• action — noun
• active — adjective
• actively — adverb
• activate — verb
• actor — noun

2. Beauty

• beauty — noun
• beautiful — adjective
• beautifully — adverb
• beautify — verb

3. Courage

• courage — noun
• courageous — adjective
• courageously — adverb
• encourage — verb
• encouragement — noun

4. Success

• success — noun
• succeed — verb
• successful — adjective
• successfully — adverb

A word family consists of words derived from a common root but used in different grammatical roles.

Compounding is the formation of a new word by joining two or more complete words. The resulting compound has a distinct meaning.

Major written forms are:

• Closed compounds: Written as one word, such as blackboard, toothpaste, and football.
• Hyphenated compounds: Joined with a hyphen, such as mother-in-law, well-known, and part-time.
• Open compounds: Written as separate words but treated as one unit, such as post office, high school, and ice cream.

Compounds may also be classified grammatically:

• Noun compounds: classroom
• Adjective compounds: world-famous
• Verb compounds: proofread

The meaning of a compound is sometimes different from the literal meanings of its separate elements.

• Clipping shortens a longer word without changing its basic meaning.
  • advertisement → ad
  • examination → exam
  • laboratory → lab
• Blending combines parts of two words.
  • breakfast + lunch → brunch
  • smoke + fog → smog
  • motor + hotel → motel
• An acronym is formed from initial letters and pronounced as a word.
  • NASA, UNESCO, RADAR
• An initialism is also formed from initial letters, but each letter is pronounced separately.
  • BBC, ATM, USA

The main distinction is that clipping shortens one word, blending merges parts of words, and acronyms or initialisms use initial letters.

Conversion, also called zero derivation, occurs when a word changes its grammatical class without any visible change in form.

Examples:

• email as a noun: I received an email.
• email as a verb: Please email the report.
• bottle as a noun: The bottle is empty.
• bottle as a verb: They bottle fresh juice.

Difference from affixation:

• In conversion, no prefix or suffix is added: water (noun) → water (verb).
• In affixation, an affix is added: happy → unhappy or happy → happiness.

Conversion is especially common when nouns become verbs and verbs become nouns. The word's role is determined by its position, function, and context in the sentence.

The same word may function as a noun in one sentence and as a verb in another. This commonly occurs through conversion.

Clues for identifying a noun:

• It may follow a determiner: a call, the answer, this work.
• It may be modified by an adjective: a long walk.
• It may form a plural: calls, answers, walks.
• It may serve as the subject or object of a sentence.

Clues for identifying a verb:

• It may follow a subject: She calls.
• It can show tense: call, called, calling.
• It may follow a modal verb: can call, will work.
• It may take an object: answer the question.

Therefore, the grammatical function of a word depends on its use in context rather than on its spelling alone.

Book

• Noun: I borrowed a book from the library. Here, book names an object and is the object of borrowed.
• Verb: We will book our tickets tomorrow. Here, book means to reserve and follows the modal will.

Water

• Noun: The water is cold. Here, water names a substance and is the subject.
• Verb: Please water the plants. Here, water expresses an action.

Answer

• Noun: Her answer was correct. Here, answer names a response and is the subject.
• Verb: You should answer the question. Here, answer expresses the action of responding.

Context and sentence position reveal whether each word is a noun or a verb.

Play

• Noun: The students performed a play.
• Verb: The children play outside.

Work

• Noun: Her work is impressive.
• Verb: They work in a hospital.

Call

• Noun: I received a call from my friend.
• Verb: Please call me tonight.

Walk

• Noun: We went for a walk.
• Verb: We walk to school every day.

Smile

• Noun: She had a cheerful smile.
• Verb: The children smile at their teacher.

In the noun sentences, the highlighted words name things, activities, or expressions. In the verb sentences, they describe actions.

(a) They dance every evening.

• Dance is a verb because it expresses the action performed by the subject they.

(b) The dance was enjoyable.

• Dance is a noun because it follows the determiner the and serves as the subject.

(c) Please light the candle.

• Light is a verb because it expresses an action and takes the candle as its object.

(d) The light is bright.

• Light is a noun because it follows the and serves as the subject.

(e) We plant trees in July.

• Plant is a verb because it describes what we do. In another context, as in This plant is healthy, it would be a noun.

Some two-syllable words have the same spelling as nouns and verbs but differ in word stress.

• record: noun REcord; verb reCORD
• permit: noun PERmit; verb perMIT
• present: noun PREsent; verb preSENT
• increase: noun INcrease; verb inCREASE

Examples:

• The singer released a new REcord. The technician will reCORD the performance.
• You need a PERmit. They will not perMIT entry.
• She received a PREsent. She will preSENT the report.

The noun commonly receives stress on the first syllable, while the verb receives stress on the second. Context and sentence structure still remain essential for identifying the grammatical function.

Affixation forms a new word by adding a prefix or suffix to a root or stem.

Examples:

• teach → teacher: the verb becomes a noun through -er.
• modern → modernize: the adjective becomes a verb through -ize.
• courage → encourage: the noun becomes a verb through en-.

Conversion changes a word's grammatical category without adding an affix.

Examples:

• bottle as a noun → to bottle as a verb
• reply as a verb → a reply as a noun
• host as a noun → to host as a verb

Comparison:

• Both processes expand vocabulary and may change a word's part of speech.
• Affixation changes the word's visible form.
• Conversion leaves the form unchanged.
• Conversion depends strongly on context, while affixes often provide visible clues to grammatical category.

The sentence contains words that function as both nouns and verbs through conversion.

• The first coach is a noun. It follows the determiner the, serves as the subject, and refers to a person.
• The second coach is a verb. It follows the modal will and means to train or instruct.
• The first match is a noun. It follows their first and refers to a sporting contest.
• The second match is a verb. It follows to and means to equal the opponents' skill.

No affix has been added to change either word. Their grammatical roles and meanings are revealed by determiners, modal verbs, infinitive markers, and their positions in the sentence.

• give advice → advise
  • The teacher gave me advice. → The teacher advised me.
• make a decision → decide
  • We made a decision to leave. → We decided to leave.
• provide an answer → answer
  • She provided an answer to the question. → She answered the question.
• give support → support
  • They gave support to the plan. → They supported the plan.
• make an attempt → attempt
  • He made an attempt to climb the wall. → He attempted to climb the wall.

The rewritten versions use verbs instead of noun phrases. Tense endings may be required, and unnecessary support verbs and prepositions may be removed.

Context provides grammatical and meaning clues that show whether a word is a noun or a verb.

• Drink
  • Noun: She ordered a cold drink. The determiner and adjective identify a noun.
  • Verb: They drink tea daily. Its position after the subject identifies a verb.
• Visit
  • Noun: Our visit was brief. The possessive determiner identifies a noun.
  • Verb: We visit our grandparents weekly. The word expresses an action.
• Promise
  • Noun: He made a promise. The article identifies a noun.
  • Verb: I promise to help. The word functions as the predicate.
• Report
  • Noun: The report is complete. It is the subject.
  • Verb: Please report the incident. It is an imperative verb.

Thus, determiners, modifiers, tense, sentence position, and intended meaning prevent confusion.

• unfriendly: Formed by prefixation and suffixation: un- + friend + -ly. It is an adjective meaning not friendly.
• classroom: Formed by compounding from class + room. It functions as a noun.
• brunch: Formed by blending parts of breakfast and lunch. It normally functions as a noun.
• exam: Formed by clipping the word examination. It functions as a noun.
• email: Originally formed from electronic + mail. Through conversion, it can be a noun or a verb: an email and to email.
• teacher: Formed by suffixation: teach + -er. The suffix changes the verb into a noun referring to a person who teaches.

These examples demonstrate that English uses several productive processes to create vocabulary and assign grammatical roles.
