Vocabulary is the set of words we know and use while speaking, reading, writing, and understanding a language. In English, building a good vocabulary helps us communicate clearly and understand ideas more easily.
Rules for Building Vocabulary
Understanding vocabulary is important for solving verbal ability questions. Instead of memorizing meanings, it is better to use logical techniques to understand words. The following rules help in identifying the correct meaning of unfamiliar words.
1. Use the Context First Rule
The meaning of a word should never be decided in isolation. Always understand the context of the sentence.
Example: The judge was lenient with the offender.
Here, the context is related to punishment, so lenient means not strict.
2. Use Prefix, Root, and Suffix
Break unfamiliar words into smaller parts to understand their meaning.
Some Common Prefixes:
| Prefix | Meaning |
|---|---|
| anti | against |
| bene | good |

| pre | before |
| post | after |
Some Common Suffixes:
| Suffix | Meaning |
|---|---|
| -ology | study of |
| -phobia | fear |
| -less | without |
Example: Benevolent = bene (good) + volent (wishing) → kind
