Derivation is the process of using existing elements — bases, prefixes and suffixes — to form new bases, prefixes and suffixes.

Derivation is not as simple as simply concatenating elements. There are rules that one must follow in order to derive a new element.

Prefix+Prefix and Suffix+Suffix: Concatenate the two elements: tro+ + po+ = tropo+

Prefix+Base: Concatenate the prefix onto the base: tro+ + bon* = trobon*

Base+Suffix: Replace the base wildcard (*) with the suffix: bon* + -ult* = bonult*.

Base+Base: Concatenate with an infix based on the part of speech and tense of the modification:

Type of Concatenation Infix Example
Noun -o+ pisk* "fish" + qr* "group" = piskoqr* "school of fish"
Adjective, present tense -i+ dw* "two" + kmt* "tens" = dwikmt* "twenty"
Adjective, past tense -a+
Adverb -e+ bon* "good" + * "" = bone_* " well"

Prefix+Suffix: Concatenate the elements with s*.
