A suffix is a morpheme that cannot stand alone, but rather must be appended to a base. The new base has a meaning that is similar to the meaning of the base but influenced by the suffix.

A suffix is represented as a series of letters prepended with a dash ("-") and terminated with an asterisk ("*"). The pound sign represents the base to which the suffix is attached, and the asterisk serves the same function as for the original base. Note that any base can become a suffix by prepending -i+.

Suffixes are widely used to construct new bases. In general, these derivatives are etymologically related to their source bases.
