Share capital refers to the total amount of capital raised by a company through the issuance of shares to its shareholders. It represents the actual amount of money invested by the shareholders in the company. On the other hand, nominal capital refers to the authorized capital of a company, which is the maximum amount of capital that a company is authorized to raise through the issuance of shares. It is the amount stated in the company's memorandum of association and represents the company's potential capital base. In summary, share capital is the actual amount of capital raised, while nominal capital is the maximum amount of capital authorized to be raised. **

Nominal expressions are linguistic constructions that function as nouns in a sentence. They can consist of single words or phrases that act as the subject, object, or complement of a sentence. Nominal expressions can refer to people, places, things, ideas, or concepts. They play a crucial role in sentence structure and help convey meaning in a clear and concise manner. **

Nominal groups are phrases that function as a single unit in a sentence and typically consist of a noun or pronoun along with any associated modifiers. These groups can serve as subjects, objects, or complements in a sentence.
