1. Its vs. It’s

• Mistake: Mixing up “its” (possessive form) and “it’s” (contraction of “it is”).
• Tip: Always use “it’s” for “it is” or “it has.” If not, use “its.”

2. There, Their, and They’re

• Mistake: Confusing “there” (location), “their” (possessive form of they), and “they’re” (contraction of “they are”).
• Tip: Remember: “there” for places, “their” for possession, “they’re” for “they are.”

3. Your vs. You’re

• Mistake: Using “your” (possessive) instead of “you’re” (contraction of “you are”).
• Tip: Replace with “you are” to check. If it fits, use “you’re.”

4. Subject-Verb Agreement

• Mistake: Mismatching the subject and verb, especially with plural subjects.
• Tip: Singular subjects = singular verbs (e.g., “He runs”). Plural subjects = plural verbs (e.g., “They run”).

5. Affect vs. Effect

• Mistake: Confusing “affect” (verb) and “effect” (noun).
• Tip: “Affect” is an action; “effect” is a result. Think “A” for action, “E” for end result.

6. Then vs. Than

• Mistake: Misusing “then” (refers to time) and “than” (used for comparisons).
• Tip: “Then” relates to time, while “than” is for comparisons.

7. Who vs. Whom

• Mistake: Using “who” instead of “whom” and vice versa.
• Tip: Use “who” as the subject (e.g., “Who called?”) and “whom” as the object (e.g., “To whom did you speak?”).

8. Loose vs. Lose

• Mistake: Confusing “loose” (adjective meaning not tight) with “lose” (verb meaning to misplace or fail to win).
• Tip: “Loose” rhymes with “goose.” “Lose” has a “z” sound, like “snooze.”

9. Fewer vs. Less

• Mistake: Using “less” with countable nouns and “fewer” with uncountable nouns.
• Tip: “Fewer” for countable items (e.g., “fewer apples”), “less” for uncountable (e.g., “less water”).

10. Me vs. I

• Mistake: Incorrectly using “me” instead of “I” and vice versa.
• Tip: Use “I” for subjects (e.g., “John and I”) and “me” for objects (e.g., “to John and me”).
