Identify the misspelt word
- (a)Mnemonic
- (b)Occassionally
- (c)Surveillance
- (d)Bureaucracy
Answer
Why
Correct — B. The correct spelling is occasionally: double c, single s.
Build it from its parts: occasion + -al + -ly. Occasion has cc and one s, and -al followed by -ly gives the double l at the end.
Occassionally doubles the s, so it is the misspelt word → option (b). Mnemonic, Surveillance and Bureaucracy are all spelt correctly.
Why the others are wrong
- (a)Mnemonic — Mnemonic is correct. It begins with a silent m, from Greek mnēmōn, 'mindful', so the mn- opening is right.
- (c)Surveillance — Surveillance is correct. It comes from French surveiller, 'to watch over', which is why it keeps the -eill- cluster: e, i, double l.
- (d)Bureaucracy — Bureaucracy is correct: bureau, with its eau kept whole, plus -cracy, 'rule', as in democracy.
Concept
Spell long words by their parts. Occasionally is occasion + al + ly, and each part keeps its own letters: cc and a single s in occasion, the l of -al, the l of -ly.
The other words reward the same habit. Surveillance is sur + veill + ance, bureaucracy is bureau + cracy, and mnemonic keeps the Greek mn- at its start.
Accommodate makes a useful contrast: it doubles both c and m. Occasion doubles only its c.
Key facts
- Occasion has double c and single s.
- Occasionally is occasion + -al + -ly, which is why it ends in double l.
- Mnemonic starts with a silent m, from Greek mnēmōn, 'mindful'.
- Surveillance comes from French surveiller, 'to watch over'.

Common traps
- Doubling the s by analogy with possession, which really does have ss
- Suspecting Mnemonic because its mn- opening looks odd, when it is correct
