A preposition connects a noun or a pronoun with some other words in a sentence. It shows the relationship between the noun or pronoun and the other words.

We start a sentence with a capital letter. A direct quotation, salutation and closing of a letter also start with capital letters. Rule 1: Capitalise the first word of every sentence.

In the last chapter, we learned about adjectives that modify nouns and pronouns. In a similar way, an adverb is also a modifier. It modifies verbs, adjectives and adverbs. Adverbs are words that modify or describe verbs, adjectives and adverbs.

The passive voice is formed with the verb to be + the past participle of the main verb. When the agent (the person who carries out the action) is unknown, unimportant or obvious from the context.
