ENV05 — Idioms, Proverbs & Phrases
📚 Chapter ENV05 · NDA Vocabulary LevelNDA Level
📌 How Idioms Are Tested: The question gives an idiom or phrase and four options. Three options are wrong — they use the literal meaning, a military-sounding trap, or a similar-sounding but incorrect meaning. One option gives the exact figurative meaning. The key rule: idioms are never literal. Never pick the option that describes the physical action of the words.
💡 Strategy: Step 1 — Know the figurative meaning before reading options. Step 2 — Eliminate literal interpretations immediately. Step 3 — Eliminate military or technical-sounding options that seem plausible but are literal. Step 4 — Confirm the figurative meaning against the correct option.
