Collective Nouns
   A collective noun names a group of individuals as if they were one individual. Singular in form, it is plural in meaning.

  The collective noun is considered either as a singular or as plural, depending on the purpose it serves.

examples: The committee was unanimous.
(That is, the committee acted as a unit, as a single individual.)
(That is, the committee were obviously acting as individuals, not as a unit.)

Inflection - Inflection denotes the change in spelling that a word undergoes to show a change in meaning. Noun inflection, which is termed declension, shows changes in number (man - men), gender (man - woman), and case (man - man's)
