Select the most appropriate synonym of the given word: IMPLACABLE
- (a)Soft
- (b)Unyielding
- (c)Flexible
- (d)Gentle
Answer
Why
Correct — B. Implacable means impossible to appease: an implacable enemy cannot be calmed, bought off or talked round.
Unyielding means refusing to give way under pressure. Someone who will not be placated will not yield, so the two share a core sense → option (b).
The word splits cleanly: im-, 'not', plus placable, 'able to be appeased', from Latin placare, 'to appease'.
Why the others are wrong
- (a)Soft — Soft describes someone lenient or easily moved, which is exactly what an implacable person is not. It sits on the yielding side of the scale.
- (c)Flexible — Flexible means ready to bend or adapt, the direct opposite of the keyed Unyielding. An implacable opponent does not bend, so this points the wrong way.
- (d)Gentle — Gentle means mild and kind in manner. Implacable describes hostility that cannot be softened, so Gentle is nearer an antonym than a synonym.
Concept
A synonym item is decided by the word's core sense. For implacable that sense is refusal: anger or opposition that cannot be appeased or relaxed.
Look at how the options divide. Soft, Flexible and Gentle all describe someone who gives way. Unyielding stands alone on the other side, with implacable.
When the word is unfamiliar, split it. im- negates, as in impossible, and placable means 'able to be appeased'. 'Not able to be appeased' leads straight to unyielding.
Implacable can describe a force as well as a person, as in an implacable advance, meaning relentless and unstoppable. The sense is the same, something that will not relent, and it still matches Unyielding.
