Punctuation
A sentence is a set of words that expresses a complete thought. It tells us, who or what the sentence is about and what happened. We use sentences to communicate facts, views and ideas.
Capital Letter and Full stop (.)
We begin a sentence with a capital letter and full stop is used to mark the end of a sentence.
For Example:
The Earth revolves around the Sun. (Fact)
Eating green vegetables makes our bones strong. (Opinion)
Note
We write the names of particular persons, objects, events and places in capital letter.
For Example:
We are going to Delhi.
Dia bought a new dress.
Question mark ( ? )
Sentences that ask questions begin with capital letter and end in a question mark.
For example:
What is your name?
Where do you live?
