https://www.egrammatics.com/what-is-a-noun/types-of-nouns/collective-nounØ Some collective nouns appear to be singular but, are plural in meaning and take plural verbs→. Cattle, Police, Women, Men, Children, People, Crowd, Poultry, Clergy, Gentry, Infantry, Cavalry, and Vermin. Since these nouns are already plural, we never add the suffix ‘-s’ to them to form their plurals. Words like cattles, womens, childrens, crowds, gentries, etc do not exist.
