📖 Let’s Learn One-Word Substitution!
One-word substitution means replacing a long phrase or description with a single word. For example: “A person who speaks many languages” = polyglot. “A person who loves books” = bibliophile.
This is one of the most tested topics in competitive exams like Olympiads, NTSE, and scholarship tests. It also builds your vocabulary dramatically — each word you learn is worth an entire phrase!
