Word formation is the process of creating new words from existing ones by adding parts or combining words. It is a crucial skill in verbal reasoning, especially in competitive exams, because it helps you understand unfamiliar words and expand your vocabulary quickly. By learning how words are formed, you can guess meanings, identify correct word forms, and improve your comprehension.
At the heart of word formation are root words (also called base words), which carry the main meaning. By adding prefixes (beginnings) or suffixes (endings), or by joining two words together, new words with different meanings or grammatical roles are created.
Understanding these building blocks will help you decode complex words and use them correctly.
A prefix is a group of letters added to the beginning of a root word to change its meaning. Prefixes do not usually change the part of speech of the word but often create the opposite or a related meaning.
For example:
| Prefix | Meaning | Example Word | Meaning of Example |
|---|---|---|---|
| un- | not, opposite | unfair | not fair |
| re- | again | rebuild | build again |
| dis- | not, opposite of | dislike | not like |
| pre- | before | preview | view before |
A suffix is a group of letters added to the end of a root word. Suffixes often change the part of speech of the word (for example, from an adjective to a noun) and sometimes change the meaning.
For example:
| Suffix | Effect | Example Word | Part of Speech |
|---|---|---|---|
| -tion | Forms nouns | creation | Noun |
| -ment | Forms nouns | enjoyment | Noun |
| -ly | Forms adverbs | slowly | Adverb |
| -ness | Forms nouns | kindness | Noun |
Compounding is the process of combining two or more words to form a new word with a specific meaning. The new word often has a meaning related to the original words but is treated as a single word.
Examples include:
Compounds can be written as one word, hyphenated, or as separate words, but in competitive exams, you will mostly encounter solid compounds (one word).
When forming new words, spelling changes often occur. These changes follow specific rules to maintain correct pronunciation and spelling.
Common spelling changes include:
Meaning changes can be subtle or significant. For example, adding un- usually reverses the meaning, but some prefixes like re- imply repetition.
| Root Word | New Word | Rule Applied | Meaning Change |
|---|---|---|---|
| hope | hopeful | Drop 'e' before adding '-ful' | Having hope |
| happy | unhappy | Prefix 'un-' added | Not happy |
| run | running | Double consonant before '-ing' | Action of running |
Step 1: Identify the root word: 'happy' (an adjective meaning feeling joy).
Step 2: Add the prefix 'un-' which means 'not' or 'opposite of'.
Step 3: Combine: un + happy = unhappy.
Step 4: Meaning changes from 'feeling joy' to 'not feeling joy'.
Answer: 'Unhappy' means 'not happy'.
Step 1: Identify the root word: 'move' (a verb meaning to change position).
Step 2: Add the suffix '-ment' which forms nouns indicating an action or result.
Step 3: Combine: move + ment = movement.
Step 4: The word changes from a verb to a noun meaning 'the act or process of moving'.
Answer: 'Movement' is a noun derived from the verb 'move'.
Step 1: Identify the two words: 'note' (a brief record) and 'book' (a set of pages).
Step 2: Join the two words to form a compound word: notebook.
Step 3: The new word means 'a book used for writing notes'.
Answer: 'Notebook' is a compound word meaning a book for notes.
Step 1: Identify the root word: 'hope'.
Step 2: The suffix '-ful' begins with a vowel.
Step 3: According to spelling rules, drop the final 'e' of the root word before adding the suffix.
Step 4: Combine: hop + e + ful -> hope + ful -> hopeful (dropping 'e').
Step 5: Meaning changes to 'full of hope'.
Answer: 'Hopeful' is formed by dropping 'e' and adding '-ful'.
Step 1: Identify the word 'happyness' which seems to be a noun form of 'happy'.
Step 2: Check the correct suffix for forming noun from 'happy' is '-ness', not '-yness'.
Step 3: Correct spelling is 'happiness'.
Step 4: Replace 'happyness' with 'happiness' in the sentence.
Answer: Correct sentence: "She is very happiness about the results." However, grammatically better is "She is very happy about the results."
