    • 2009, Brandon C. Look, “Symbolic Logic II, Lecture 2: Set Theory”, in[1], archived from the original on 19 June 2018:
      For any infinite set, there is a 1-1 correspondence between it and at least one of its proper subsets. For example, there is a 1-1 correspondence between the set of natural numbers and the set of squares of natural numbers, which is a proper subset of the set of natural numbers.
  6. (grammar) Not limited by person or number. [from 19th c.]
  7. (music) Capable of endless repetition; said of certain forms of the canon, also called perpetual fugues, constructed so that their ends lead to their beginnings.[1]

Usage notes[edit]

Although the term is incomparable in the precise sense, it can be comparable both in mathematics and set theory to compare different degrees of infinity, and informally to denote yet a larger thing.

Poets (and particularly hymn-writers before the 20th century) would commonly rhyme the word as though pronounced [-ɑɪnɑɪt] and church congregations still on occasion adopt that pronunciation.
