. Choose the correct one-word substitute for: 'Extremely old-fashioned; belonging to a time before the biblical flood'.
Answer & explanation
Answer: C) Antediluvian
'Antediluvian' literally means 'before the deluge' — i.e., before Noah's flood, hence extremely old-fashioned.
'Obsolete' means out of use; 'Medieval' refers to the Middle Ages; 'Tale' means a story.
Hence the precise substitute is 'Antediluvian'. - SSC Steno 2026 T-1 Spelling
Identify the misspelt word.
Answer & explanation
Answer: B) Antedeluvean
Meaning: the misspelt word is Antedeluvean. The correct spelling is antediluvian = belonging to the age before the Biblical Flood, and so hopelessly old-fashioned *(जलप्रलय-पूर्व, अति प्राचीन, दक़ियानूसी)*.
Rule: split a long Latin word into its parts and each part fixes its own vowels.
ante- = before (antecedent, antenatal) + diluvium = flood + -ian = the adjective ending.
The paper's form breaks it twice: it writes de- where the flood root needs di-, and -ean where the ending must be -ian.
Compare *Elizabethan*, *Victorian*, *Edwardian* — the *-ian* ending is the regular one here.
Why the others are fine.
• sesquipedalian = given to using very long words; literally 'a foot and a half long' - SSC Steno 2026 T-1 Spelling
Fill in the blank with the correctly spelt word.
The king ruled with ________ authority.Answer & explanation
Answer: B) antediluvian
Meaning: antediluvian = belonging to the age before the Biblical Flood; hence extremely old or hopelessly out of date *(अति प्राचीन, बाढ़-पूर्व काल का, पुराने ज़माने का)*.
A king whose authority is called antediluvian rules in an old, long-outdated way.
Build it from its parts.
• Latin ante = before — the prefix is ante-, with an e.
• Latin diluvium = a flood — the root is -diluvi-, with an i in both syllables.
• ante + diluvi + an = antediluvian.
Why the others are wrong.
• antidiluvian — anti- means *against* *(विरुद्ध)*, so this would read "opposed to a flood", not "before the flood".
• antedeluvian — the root is diluvi, not *deluvi*, even though English *deluge* *(प्रलय, जलप्रलय)* tempts
Examples
- “His antediluvian views on technology surprised the young staff.”
