Vocabulary Building for UPSC English Compulsory

Vocabulary drives four of the five UPSC English Compulsory sections — comprehension answers, precis paraphrase, translation word-choice, and essay range. A 3,000-word active vocabulary is more than enough; most graduates already possess 2,000 and need to push the remaining 1,000 over two to three months.

Active vs Passive Vocabulary

Passive vocabulary is what you recognise when you read. Active vocabulary is what you produce when you write. UPSC rewards active vocabulary — a word you have used in two sentences is yours; a word you have only seen is not.

The Two-Sentence Method

For every new word, write two sentences — one that copies the context of your reading, and one that invents a new context. The second sentence is the test of ownership.

Example: sanguine — “The finance minister remained sanguine about growth despite the slowdown.” | “Despite repeated interview rejections, she was sanguine that the next one would be different.”
