Proposed Definition<br />

Infinity. When followed by a number, it denotes a transfinite cardinal, such as ℵ₀. <br /> <br />

Usage Examples<br />

<br />

ci'i da mulna'usle

There are infinitely many prime numbers.<br />

<br />

Notes<br />

<br /> <br />

Issues<br />

As multiplication and exponentiation of transfinite ordinals is incompatible with that of cardinals, a new cmavo should be added for a transfinite ordinal, such as ω₀.<br /> <br />

<br />

cmavo ka'o (PA5)<br />

<br />

Proposed Definition<br />

i, imaginary unit. When followed by a real number, multiplies that number by i. If four real numbers are separated by three ka'o, the number is a quaternion, with the components in the order 1, i, j, k.<br /> <br />
