💬 How to Make Interrogative and Declarative Sentences in English (The Fun, Smart Way!)

Learning how to make interrogative (question) and declarative (statement) sentences is one of the first big steps toward mastering English.
It’s a skill that powers everything — from everyday chats to essays, from confident speaking to strong reading comprehension.

In this guide, we’ll walk you through everything you need to know — how to build these sentence types correctly, what makes them different, and how you can easily practice them using tools from the Vellso app. Let’s make grammar feel simple, logical, and actually enjoyable!

 

🧩 Interrogative vs. Declarative — What’s the Real Difference?

Before jumping into the “how,” let’s clear up the “what.”

A declarative sentence gives information. It’s calm, factual, and tells the listener something:

“She reads books.”

An interrogative sentence asks for information. It’s curious, alive, and invites a response:

“Does she read books?”

Simple, right? But behind these small differences lies one of the most important structures in English grammar — word order.
When you can control word order and auxiliary verbs, you can turn any thought into a question or a statement like a pro.

That’s exactly what the Vellso Super App helps you do: it doesn’t just show the rules; it trains your brain to feel them through interactive lessons and realistic conversation drills.

 

✏️ Building Declarative & Interrogative Sentences — Step by Step

Let’s start with the basics.

🟢 Declarative Sentences (Statements)

These sentences usually follow a simple pattern:
Subject + Verb + Object

“She reads books.”
“They live in Paris.”

No tricks here — declarative sentences are about giving information clearly.

🔵 Interrogative Sentences (Questions)

Now we add a small twist: auxiliary verbs (like do, does, is, are, will) and sometimes change the word order.

“Does she read books?”
“Do they live in Paris?”

You just moved from a fact to a question — and that’s the magic of structure.

💡 Vellso Tip:

🗣️ Turning Statements into Questions — Like a Native Speaker

When you want to ask something in English, you can’t just raise your tone — you need to move the right words.

Example:
Declarative → “She works hard.”
Interrogative → “Does she work hard?”

Here’s what changed:

• We added the auxiliary verb does

• We moved it before the subject

• We used the base form work (not works)

That’s it! 🎉

But there’s more:

• Yes/No Questions start with auxiliaries (Do you like it? Is she happy?)

• Open-ended Questions start with Wh- words (What, Where, When, Why, How)

“Where does she work?”
“Why is she tired?”

💬 Practice Makes Fluent:
In Vellso’s Conversation Section, you can hear native speakers use these exact sentence types — then record yourself and compare pronunciation instantly. It’s a fun way to train your ear and your instinct at the same time.

 

🎯 Mastering the Grammar Game — Structure Made Simple

Here’s a quick cheat sheet:

Sentence Type	Word Order	Example
Declarative	Subject + Verb + Object	She studies English.
Interrogative	Auxiliary + Subject + Verb + Object	Does she study English?

The secret is consistency. Once you get this rhythm, you’ll start to notice patterns in movies, songs, and even text messages.

💡 Vellso Advantage:
Each Vellso lesson includes a Grammar Focus and Practice Section that show these patterns in real-life examples. You can practice turning statements into questions, and the app gives you instant feedback — green for correct, red for “try again.” Learning becomes a mini-game that’s hard to stop playing.

 

🔍 Spot the Difference — Declarative vs. Interrogative in Action

Let’s look at them side by side:

Declarative	Interrogative
They live in Paris.	Do they live in Paris?
She’s a teacher.	Is she a teacher?
He likes music.	Does he like music?

Notice how interrogatives just shift the balance — either through an auxiliary verb or by flipping the order.

If you want to ask open-ended questions, add a Wh- word:

“Where do they live?”
“Why does he like music?”

It’s all about patterns, not memorization!

And guess what — Vellso’s Drilling Practice and Memory Box are designed exactly for that. Through repetition spaced at scientifically optimized intervals, your brain naturally starts producing correct sentences without hesitation!🥳💥
