使用する際の注意点

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.
