Introduction
This final chapter covers two remaining high-frequency areas — correct spelling and confusing word-usage
pairs — and closes with a consolidated mixed-rules revision that draws together concepts from every
previous chapter, the way SSC's actual previous year papers combine them.
Commonly Misspelled Words
| Correct Spelling | Common Misspelling |
|---|
| Accommodate | Accomodate |
| Necessary | Neccessary |
| Occurrence | Occurence |
| Embarrass | Embarass |
| Definitely | Definately |
| Separate | Seperate |
| Recommend | Reccomend |
| Privilege | Privelege |
| Rhythm | Rythm |
| Maintenance | Maintainance |
Commonly Confused Word-Usage Pairs
| Word | Meaning | Word | Meaning |
|---|
| Advice | Noun (suggestion) | Advise | Verb (to suggest) |
| Practice | Noun (British spelling) | Practise | Verb (British spelling) |
| Lose | To not win / misplace (verb) | Loose | Not tight (adjective) |
| Its | Possessive (belonging to it) | It's | Contraction of "it is" |
| Your | Possessive | You're | Contraction of "you are" |
| Then | Time sequence | Than | Comparison |
| Quiet | Silent | Quite | Fairly/very |
Q. Choose the correct sentence: (A) Its raining outside. (B) It's raining outside.
"It's" here is a contraction of "it is" — needed before "raining"
Correct: (B) It's raining outside.
American vs British Spelling
| British | American |
|---|
| Colour | Color |
| Organise | Organize |
| Centre | Center |
| Defence | Defense |
💡 Exam Note: SSC generally accepts British spelling conventions as standard — stay consistent with one style throughout a single piece of writing if given a choice.
Mixed Grammar Revision Drill
Q. Spot the error: "One of my friend / have decided / to start / a new business."
"One of my [plural noun]" needs a plural noun (Ch. 2) AND a singular verb since "One" is the true subject (Ch. 6)
Errors: "friend" should be "friends"; "have" should be "has"
Q. Choose the correct sentence combining tense and preposition rules: (A) She has been working here since five years. (B) She has been working here for five years.
"Five years" is a DURATION, not a specific starting point → needs "for," not "since" (Ch. 5)
Correct: (B) She has been working here for five years.
Q. Choose the correct sentence: (A) Neither the manager nor the employees was informed. (B) Neither the manager nor the employees were informed.
"Neither...nor" agreement follows the NEARER subject ("employees," plural) (Ch. 6 & 11)
Correct: (B) Neither the manager nor the employees were informed.
How to Use Previous Year SSC Questions
⚠️ Study Strategy: Previous year SSC English questions are the single best practice resource because they reveal exactly which rule-combinations (like the three mixed examples above) SSC repeatedly favours — after finishing all 23 chapters, dedicate focused practice time to solving actual previous year papers under timed conditions.
✅ Practice Focus: High-frequency misspelled words · Confusing word-usage pairs (its/it's, then/than, advice/advise) · British vs American spelling awareness · Combining multiple grammar rules in a single sentence (as SSC's real questions do) · Timed practice with actual previous year papers.
