Sadreɪl has extensive use of both bound and unbound morphemes in its grammar. Unbound morphemes are called "cores", being a noun, verb, "relators", or adjective (Descriptors). Bound morphemes are collectively called, "Particles", divided into unit effecting particles and sentence effecting particles.
"Every morpheme can be classified as either free or bound.[2] These categories are mutually exclusive, and as such, a given morpheme will belong to exactly one of them.
- Free morphemes can function independently as words (e.g. town, dog) and can appear within lexemes (e.g. town hall, doghouse).
- Bound morphemes appear only as parts of words, always in conjunction with a root and sometimes with other bound morphemes. For example, un- appears only accompanied by other morphemes to form a word. Most bound morphemes in English are affixes, particularly prefixes and suffixes. Examples of suffixes are -tion, -ation, -ible, -ing, etc. Bound morphemes that are not affixes are called cranberry morphemes." -wikipedia
