Master These 10 Common Grammar Errors

1Countable vs Uncountable Nouns

The Rule: Use “a few” with countable nouns (things you can count) and “a little” with uncountable nouns (things you can’t count individually).
✓ A few friends (countable)
VS
✓ A little water (uncountable)
💡 Memory Trick: If you can put a number in front of it (1 friend, 2 friends), use “a few” or “many.” If you can’t (you don’t say “1 water, 2 waters”), use “a little” or “much.”

2Subject-Verb Agreement with “Neither”

The Rule: “Neither” is always singular, even when followed by a plural noun. It means “not one or the other.”
📝 Examples:
✓ Neither of the answers is correct
✗ Neither of the answers are correct
✨ Pro Tip: Words like “neither,” “either,” “each,” and “every” are always singular. Think of them as emphasizing individual items, not groups.

3Relative Pronouns: Who, Whose, Whom

The Rule:
  • Who = subject (does the action)
  • Whose = possession (shows ownership)
  • Whom = object (receives the action)
📝 Examples:
The woman whose car was stolen (her car)
The man who called me (he called)
The person whom I met (I met him)
💡 Quick Test: If you can replace it with “his/her,” use “whose.”

4Question Tags

The Rule: If the statement is negative, the tag is positive. If the statement is positive, the tag is negative. They balance each other!
He didn’t go, did he?
VS
He went, didn’t he?
📝 More examples:
• You are coming, aren’t you?
• She can’t swim, can she?
• They will help, won’t they?

5Where, When, Which

The Rule:
  • Where = places/locations
  • When = time
  • Which = things/objects
📝 Examples:
The restaurant where we ate (location)
The day when we met (time)
The book which I bought (thing)
✨ Fun Fact: You can often replace “where” with “in which” or “at which” (the place in which we met).

6Reported Speech: If vs That

The Rule: Use “if” or “whether” when reporting yes/no questions. Use “wh-words” (what, where, why) for information questions.
📝 Examples:
Direct: “Do you need help?”
Reported: She asked if I needed help.

Direct: “What is your name?”
Reported: He asked what my name was.

7Subject-Verb Agreement with “Each”

The Rule: “Each” is always singular because it emphasizes individuals separately, not as a group.
📝 Examples:
✓ Each of the players is ready
✗ Each of the players are ready

✓ Each book is different
✓ Every student has a laptop

8Than vs Then

The Rule: “Than” is for comparisons. “Then” is for time/sequence.
She’s taller than me (comparison)
VS
We ate, then left (time)
💡 Memory Trick: “Than” has an “a” like “compArison.” “Then” has an “e” like “whEn” (time).

9Since vs For

The Rule: “Since” = specific starting point in time. “For” = duration/length of time.
Since 2020 (starting point)
VS
For 5 years (duration)
📝 Examples:
• I’ve lived here since Monday (point in time)
• I’ve lived here for three days (duration)
• She’s been working since 9 AM
• She’s been working for 6 hours

10Little vs A Little

The Rule: “A little” = small amount (positive feeling). “Little” = almost none (negative feeling). Both are used with uncountable nouns.
There’s a little hope
(some hope exists ✨)
VS
There’s little hope
(almost no hope 😞)
✨ Amazing Insight: Adding just one letter “a” completely changes the meaning from negative to positive!

🎯 Final Practice Tip

The best way to master these grammar rules is to use them in your daily writing. Start noticing these patterns in books, articles, and conversations. Soon, correct grammar will become automatic!
