indefatigable in SSC previous-year questions
- SSC Selection Post Ph-14 2026 (Graduate Level) Spelling
Which of the following is the correct spelling of the word?
Answer & explanation
Answer: A) Indefatigable
Meaning: indefatigable = tireless, never giving up *(अथक, न थकने वाला)*.
Built from in- (not) + de- + Latin *fatigare* (to tire) + -able.
Build the spelling.
in-de-fat-i-ga-ble — one f, *-ga-* with no u, ending -able.
Why the others are wrong.
#B Indefatiguable — adds a u copied from *fatigue* *(थकान)*; the *u* drops before *-able*.
#B Indeffatigable — doubles the f; *de + fat* has a single f *(दोहरा f — गलत)*.
#B Indefatigible — ends in -ible; the Latin root takes -able *(गलत प्रत्यय)*.
Answer: Indefatigable
*Fatigue loses its -ue before -able: in-de-fati-gable.*
