❓ Frequently Asked Questions (FAQ)
FAQ 1
What are the most common grammar errors students make?
Show Answer
Answer: Subject‑verb agreement mistakes, wrong tense usage, incorrect prepositions, missing or wrong articles, double negatives, and misuse of adjectives/adverbs are among the most common errors.
FAQ 2
How can I avoid subject‑verb agreement errors?
Show Answer
Answer: Identify the true subject of the sentence. Remember that phrases like 'along with', 'as well as' don't change the number. Singular subjects take singular verbs; plural subjects take plural verbs.
FAQ 3
Why are prepositions so tricky?
Show Answer
Answer: Preposition usage is often idiomatic—there is no simple rule. You must learn common combinations: good at, afraid of, married to, interested in, etc. Reading a lot helps build this instinct.
FAQ 4
What is a double negative, and why is it wrong?
Show Answer
Answer: A double negative uses two negative words in the same clause (e.g., "I don't have no money"). In standard English, this cancels out the meaning. Use 'any' instead of a second negative.
FAQ 5
How can I improve my grammar quickly?
Show Answer
Answer: Practise exercises like this one regularly. Read books and articles aloud. Keep a small notebook of errors you often make and review it. Over time, your eye will catch mistakes automatically.
