Big picture
A clear sentence helps a reader understand who is doing something and what is happening. Grammar gives words their jobs and shows how those jobs fit together. Learning it through examples is more useful than memorising a name without knowing how to use it.
This chapter builds Class 6 sentence skills from nouns and pronouns to verbs, descriptions, questions and punctuation. Correct and incorrect pairs show common problems. Read the whole sentence before choosing a form, because a word's job depends on how it is used.
Learning goals
Identify sentence parts and sentence purposes.
Use nouns, plurals and possession correctly.
Choose pronouns with clear reference.
Apply basic agreement, tense and article rules.
Edit descriptions, links and punctuation in complete sentences.
Core ideas
1. Sentences, subjects and kinds of sentences
A sentence expresses a complete thought. Its subject tells us who or what the sentence is about, and its predicate says something about that subject. In “The little bird built a nest,” the subject is the little bird and the predicate is built a nest.
A statement gives information, a question asks, a command directs or requests, and an exclamation expresses strong feeling. A command can have an understood subject: “Please sit down” addresses you. Incorrect: “The bird near the window.” Correct: “The bird near the window is singing.” The first group lacks a complete predicate. Begin a formal sentence with a capital letter and end it with punctuation suited to its purpose, not with a full stop after every few words.
2. Nouns, number and possession
A noun names a person, place, animal, thing or idea. A common noun names a class, while a proper noun names a particular one and usually begins with a capital letter: city and Jaipur. Abstract nouns such as kindness name ideas or qualities.
Singular means one and plural means more than one. Many plurals add -s or -es, but child becomes children and leaf becomes leaves. Some nouns such as water are normally uncountable. Incorrect: “Three childs played.” Correct: “Three children played.” Possession can use an apostrophe: the girl's bag belongs to one girl; the girls' bags belong to several girls. Do not add an apostrophe merely because a noun is plural. The form books names several books without showing ownership.
3. Pronouns and clear reference
A pronoun can replace a noun or noun phrase. I, you, he, she, it, we and they are common subject forms; me, him, her, us and them commonly appear as objects. Incorrect: “Me carried the basket.” Correct: “I carried the basket.” Incorrect: “The teacher called Ravi and I.” Correct: “The teacher called Ravi and me.”
Possessive forms such as my, your and their accompany nouns, while mine, yours and theirs can stand without the noun. Its shows possession, while it's means it is or it has. Keep reference clear. “Asha told Ritu that she had won” may be unclear unless the context identifies she. Repeat a name when needed. Repetition is better than leaving the reader unsure who did what.
4. Verbs, agreement and helping verbs
A verb expresses an action, event or state. A helping verb works with another verb: is running, has finished, will travel. The present simple verb must agree with its subject. Incorrect: “The boys plays.” Correct: “The boys play.” Incorrect: “She walk daily.” Correct: “She walks daily.”
Use is with a suitable singular subject and are with a suitable plural subject; I takes am in the present. Has usually accompanies he, she, it or a singular noun, while have accompanies I, you, we and they. Look for the real subject rather than the nearest noun. “The box of pencils is open” has singular box as its head. Do not change the verb to are merely because pencils comes immediately before it.
5. Tenses and time words
Tense helps place actions in time. Present simple often expresses habits: “We read after lunch.” Past simple expresses a completed past event: “We read the story yesterday,” with read pronounced differently. Future can be expressed with will: “We will read tomorrow.”
The continuous form uses an appropriate form of be with an -ing verb: “She is drawing” or “They were drawing.” Time words help you choose. Incorrect: “Yesterday he walks home.” Correct: “Yesterday he walked home.” Incorrect: “They is playing now.” Correct: “They are playing now.” Not every verb follows a regular past pattern: go becomes went and eat becomes ate. Keep a short list of common irregular forms and practise them in complete sentences rather than assuming every past tense simply adds -ed.
6. Articles, adjectives and comparison
Articles a, an and the help identify nouns. Use a or an with a singular countable noun when appropriate, choosing according to sound: a uniform but an umbrella. The points to a specific item or one already identified.
An adjective describes or limits a noun: a blue kite, three books, a careful learner. Comparative forms compare two, while superlative forms pick the highest or lowest within a relevant group. Tall, taller and tallest follow a simple pattern; good, better and best are irregular. Incorrect: “This rope is more longer.” Correct: “This rope is longer.” Avoid doubling the comparison. A word's role can depend on context, so identify what it describes rather than learning that a particular spelling must always belong to one class.
7. Adverbs, prepositions and conjunctions
An adverb can describe how, when or where an action happens: “She spoke softly.” Many adverbs end in -ly, but not all do; fast can be an adverb. Incorrect: “He ran quick” in careful school usage. Correct: “He ran quickly.”
A preposition expresses a relationship such as position or time: under the desk, beside the door, after lunch. A conjunction joins words or groups. And adds, but contrasts and because gives a reason. “I carried an umbrella because rain was expected” explains a cause. Do not write “Because rain was expected” alone as a complete formal answer unless the task specifically accepts a short response. A joined sentence still needs a clear relationship, not merely a conjunction inserted between unrelated ideas.
8. Punctuation, questions and a complete editing example
Use capitals for sentence beginnings, names and I. A question mark ends a direct question. Commas can separate items in a simple list, and quotation marks indicate exact speech. An apostrophe can show possession or a contraction; these uses differ from plural formation.
Draft: “my sister have two new book she reads them quiet every evening”
Edited version: “My sister has two new books. She reads them quietly every evening.”
The changes supply a capital, singular agreement with sister, a plural after two, a sentence boundary and an adverb describing reads. Each correction has a reason. To make a question from “She is reading,” move the helping verb: “Is she reading?” With an ordinary present-simple verb, use do or does: “Does she read daily?” Keep the main verb in its base form after does, rather than writing “Does she reads?” Finally, read the edited version aloud to check that its meaning is complete.
A reliable approach to questions
Read the command word before choosing an answer. A definition needs the distinguishing feature; a comparison needs matching criteria on both sides; an application needs a reason linked to the situation.
Extract the supplied evidence and assumptions. Keep a small working table rather than relying on memory. If information is absent, state the limit instead of inventing a value or claiming certainty.
Work through the relevant rule one step at a time. For a program, record the changing state; for a scenario, connect the requirement to the feature that meets it. Explain why the closest alternative fails.
Check the result against the original question, including boundary cases, units and wording. Present a concise final answer followed by enough reasoning for another student to reproduce your conclusion.
Connections that matter
Reading comprehension depends on clear pronoun and time relationships.
Functional writing needs accurate instructions and questions.
Creative writing uses verbs and descriptions to build scenes.
Common mistakes
Adding apostrophes to ordinary plurals: books needs no apostrophe.
Agreeing with pencils instead of box: identify the head subject.
Writing more longer: use one comparative form.
Using reads after does: the main verb becomes read.
