Key Grammar Structures: How a Sentence Is Built

A sentence is built from word blocks that must stand in the right order. The basic order is subject, verb, object. Words agree with each other (one girl eats, two girls eat). Negatives and questions use a helper word, and linking words such as and, but, because join ideas. Details of quality, quantity, place and time can be added.

🎬 Step-by-step story

  1. Three coloured blocks lie in the wrong order: mangoes, eats, Mira. It does not sound right. Colours show jobs: blue is who, red is the action, green is what.
  2. The blocks slide into order: Mira eats mangoes. Subject (who), then verb (does what), then object (what). This is the basic word order.
  3. Two new blocks slide in: sweet and in summer. Sweet says what kind. In summer says when. Details make a sentence rich, but the main three stay.
  4. Purple helper blocks appear: Mira does not eat sweet mangoes. The helper does carries the tense and the verb goes back to its plain form.
  5. Now the helper jumps to the front: Does Mira eat sweet mangoes? A question puts the helper first.
  6. Free play: join two sentences with and, or press Many to change Mira to The girls and see eats turn into eat. Try every button.

🤔 Common doubts, cleared

Why can I not say "Mangoes eats Mira"?

In English the order shows who does what. The subject comes first and the object after the verb.

What does "agreement" mean?

Words match each other: one subject takes eats, many subjects take eat.

Does English have gender like Hindi or Spanish?

Only in he, she, it and his, her. Nouns do not have gender, so adjectives do not change.

Where do time and place words go?

Usually at the end: Mira eats mangoes in summer.

Why does the verb lose its s after does?

The helper does already carries it. The verb is plain: does not eat.

How do I make a question?

Put the helper first: Does Mira eat? With is/are/can/will, move that word to the front.

Word order: subject, verb, object

In English the order of words tells the meaning. "Dog bites man" and "Man bites dog" use the same words but mean different things.

Place and time words usually go at the end: Mira eats mangoes in summer. Adjectives (quality) go before a noun: sweet mangoes. Other languages may order words differently, so always check the pattern.

Agreement and gender

Agreement means words match each other.

Gender is a class of nouns (for example masculine and feminine). English hardly uses it: only he, she, it, his and her show it. Many other languages, such as Hindi, Spanish and French, give every noun a gender and the adjective and verb must match it. Learn a new noun together with its gender.

Quantity, quality, place and time

Small words add detail.

Say many mangoes but much juice: many for things you can count, much for things you cannot.

Affirmation, negation and questions

The same idea can be a statement, a no or a question.

With am, is, are, can and will there is no extra helper: She is tired. She is not tired. Is she tired?

Logical relations: linking ideas

Linking words show how two ideas are related.

Try it: write a sentence about your breakfast, then turn it into a negative, a question and a joined sentence using but.

Key formulas and definitions

Worked examples

1. Put in order: "juice / drinks / Ravi".

Ravi drinks juice. Subject (Ravi), verb (drinks), object (juice).

2. Make it negative: "Mira eats mangoes."

Mira does not eat mangoes. (does not + plain verb, so eats becomes eat.)

3. Make it a question: "The girls eat mangoes."

Do the girls eat mangoes? (the subject is many, so do, not does.)

4. Join with because: "He was late. The bus broke down."

He was late because the bus broke down.
