Infinitives; Requisites of Sentence Construction: Paragraph


An infinitive is the base form of a verb preceded by the word “to.” It can be used as a noun, an adjective, or an adverb in a sentence. Here are examples of infinitives in different roles:

  1. Noun Infinitive:
    • To learn is essential for personal growth.
    • I love to swim in the ocean.
  2. Adjective Infinitive:
    • She is eager to help.
    • The book is difficult to understand.
  3. Adverb Infinitive:
    • He worked hard to achieve his goals.
    • She spoke softly to avoid waking the baby.

Requisites of Sentence Construction:

To construct a grammatically correct sentence, certain requisites need to be considered. Here are the key requisites of sentence construction:

  1. Subject: A sentence must have a subject, which is the person, thing, or entity performing the action or being described. For example: “The cat” in “The cat is sleeping.”
  2. Verb: A sentence must have a verb, which is the action or state of being expressed in the sentence. For example: “is sleeping” in “The cat is sleeping.”
  3. Object: Some sentences include an object, which is the noun or pronoun that receives the action of the verb. For example: “The cat caught the mouse” – “mouse” is the object.
  4. Agreement: There should be agreement between the subject and verb in terms of number and person. For example: “She sings” (subject “she” matches with the singular verb “sings”).
  5. Completeness: A sentence should express a complete thought or idea. It should make sense on its own and not be a fragment. For example: “I went to the store” is a complete sentence, while “Went to the store” is a fragment.


A paragraph is a group of related sentences that develop a single topic or idea. It is a fundamental unit of writing that organizes and presents information in a coherent and logical manner. Requisites of paragraph construction include:

  1. Topic Sentence: A paragraph usually begins with a topic sentence that introduces the main idea or theme of the paragraph.
  2. Supporting Details: The topic sentence is followed by supporting sentences that provide evidence, examples, explanations, or details to support the main idea.
  3. Coherence: The sentences within a paragraph should be logically connected and flow smoothly from one to another. Transitions and cohesive devices can help achieve coherence.
  4. Unity: A paragraph should focus on a single main idea or topic. All the sentences within the paragraph should contribute to the development of that main idea.
  5. Length: A paragraph can vary in length, but it typically consists of several sentences that develop the main idea adequately. However, overly long paragraphs can be challenging to read and comprehend, so breaking them into shorter paragraphs is often advisable.
  6. Conclusion: A paragraph may end with a concluding sentence that summarizes the main point or provides a transition to the next paragraph.

By adhering to these requisites, paragraphs can effectively communicate ideas and support the overall structure and flow of a written work.
