AFCAT PYQVocabulary & Usage — AFCAT 1/2025 & 2/2025 Pattern

Q1. Antonym of “Clandestine”: (AFCAT 1 2025)

(a) Covert
(b) Furtive
(c) Overt
(d) Surreptitious

Answer: (c) Overt
Clandestine = done secretly, in a hidden manner. Antonym = overt (open, not hidden, done publicly). Options (a), (b), (d) are all synonyms of clandestine. AFCAT’s vocabulary questions often list three synonyms and one antonym — pick the odd one out.

Q2. One word substitution: “A person who is skilled at using both hands equally well” is called: (AFCAT 2 2025)

(a) Ambiguous
(b) Amphibious
(c) Ambidextrous
(d) Ambivalent

Answer: (c) Ambidextrous
Ambi = both sides + dexter = right/skill = skilled on both sides. Ambiguous = having two meanings. Amphibious = living on land and water (also used for military amphibious operations). Ambivalent = having mixed feelings. Root trick: “ambi” = both + “dexter” = skilled/right-hand = ambidextrous.

Q3. “Bite the bullet” means: (AFCAT 1 2025)

(a) To fire a weapon in combat
(b) To eat quickly before a mission
(c) To endure a painful or difficult situation stoically
(d) To show exceptional courage in battle

Answer: (c) To endure a painful or difficult situation stoically
Origin: Before anaesthesia, soldiers bit on a bullet during surgery to cope with pain. Now means: to face a difficult or unpleasant situation with courage, without complaining. AFCAT favourites this military-origin idiom as it directly relates to the ethos of a defence officer.

Q4. Synonym of “Tenacious”: (AFCAT 2 2025)

(a) Irresolute
(b) Dogged
(c) Vacillating
(d) Fragile

Answer: (b) Dogged
Tenacious = holding firmly to a purpose; not giving up. Synonyms: dogged, persistent, resolute, unyielding, steadfast. Antonyms: irresolute (option a), vacillating (option c, means undecided), fragile (option d). Root: “ten” = hold (retain, contain) → tenacious = one who holds on.

Q5. One word substitution: “A speech delivered in praise of a deceased person” is called: (AFCAT 1 2025)

(a) Epitaph
(b) Elegy
(c) Eulogy
(d) Obituary

Answer: (c) Eulogy
Eulogy = a speech or piece of writing in praise of a person, especially one who has recently died. Epitaph = words written on a tombstone (different medium — written, not spoken). Elegy = a mournful poem. Obituary = a written notice of a death in a newspaper. AFCAT tests these near-synonyms together.
