Is Nomi nalisation included in your grammar syllabus for VIIIthStd?
The process of using a verb or an adjective in its noun form, in a sentence, is known as nominalisation.
1. In the sentence,
Swimming is my hobby.
'swimming' acts as a noun as it is a gerund.
2. The verb 'broke' in sentence 1 has been converted to the noun 'breaking' in sentence 2
sentence 1: He broke my toy. So, I am upset.
sentence 2: Breaking of the toy is the reason for my being upset.
Nominalisation is covered under the topics of gerund, infinitives and participles.
