Singular and Plural Nouns

• Singular nouns refer to those objects that are single in number. Plural objects are those which can be counted as more than one.

• 'These' indicates more than one object. Thus, we need to use the plural form of 'knife.'

• In such words, 'f' is replaced by '-ves.' Thus, 'knife' changes to 'knives.'
