• Necessitude, necessitousness, necessitation, necessariness are all nouns closely related to necessity, but they tend to have narrower ranges of usage than the term necessity. The principal sense of necessitude and necessitousness is impoverishment, but the plural form of the former (necessitudes) denotes a set of circumstances which is inevitable or unavoidable. Necessitation is used to suggest necessity as a philosophical or cosmic principle. Necessariness tends to be used to stress a direct connection to the adjective necessary.
