Sentence Improvement

Parallelism ensures that similar parts of a sentence follow the same pattern. This makes the sentence easier to read and understand. If you are listing activities, they should all use the same form. For example, 'I like singing, dancing, and to swim' is incorrect. To make it parallel, it should be 'I like singing, dancing, and swimming.' This rule also applies to comparisons using words like 'than' or 'as'.

A pronoun must always match the noun it replaces. If the noun is singular, the pronoun must be singular. If the noun is masculine, the pronoun must be masculine. For example, in 'Each student must bring their own book,' the word 'their' is often considered incorrect in formal grammar. Since 'Each student' is singular, it should be 'his or her own book.' Always identify who the pronoun is referring to before choosing an option.

This is the most fundamental rule in English grammar. The verb in a sentence must match the subject in number. A singular subject (like 'He', 'She', 'It', or a single name) takes a singular verb (usually ending in 's'). A plural subject (like 'They', 'We', or 'Ram and Shyam') takes a plural verb (without 's'). For example, 'The boy plays' is correct, but 'The boy play' is wrong. Be careful with collective nouns like 'Team' or 'Family' which usually take singular verbs.
