These small grammar hacks can make speaking, writing and answering English questions much easier.
Confused between AM, IS, ARE, WAS, WERE, DO, DOES, DID, HAVE, HAS and HAD?
Stop memorising complicated grammar rules.
Just remember these simple patterns
1️⃣ AM / IS / ARE — Present
Subject Use
I am
He / She / It is
You / We / They are
Examples:
• I am ready.
• She is happy.
• They are students.
💡 HACK:
I → AM | One person/thing → IS | You/Many → ARE
2️⃣ WAS / WERE — Past
Subject Use
I / He / She / It was
You / We / They were
Examples:
• I was tired.
• He was absent.
• We were late.
💡 HACK:
One → WAS | You + Many → WERE
(Remember: “I” is the special one — I was.)
3️⃣ DO / DOES — Present Questions & Negatives
Subject Use
I / You / We / They do
He / She / It does
Examples:
• Do you play cricket?
• Do they understand?
• Does she study every day?
• He doesn't like tea.
💡 HACK:
He / She / It → DOES
Everyone else → DO
⚠️ Golden Rule:
After does, use the base verb.
❌ Does she plays?
✅ Does she play?
4️⃣ DID — Past Questions & Negatives
DID works with EVERY subject.
I / You / He / She / It / We / They → DID
Examples:
• Did you go?
• Did she call?
• Did they finish?
💡 HACK:
Past + Question/Negative = DID for everyone.
⚠️ After did, use the base verb.
❌ Did he went?
✅ Did he go?
5️⃣ HAVE / HAS — Present Possession & Present Perfect
Subject Use
I / You / We / They have
He / She / It has
Examples:
• I have a book.
• We have completed the work.
• She has a new bag.
• He has finished his homework.
💡 HACK:
He / She / It → HAS
Everyone else → HAVE
6️⃣ HAD — Past
HAD works with EVERY subject.
I / You / He / She / It / We / They → HAD
Examples:
• I had a bicycle.
• She had completed her work.
• They had already left.
💡 HACK:
Past possession / past perfect = HAD for everyone.
