The morphology of Aelatha is said to be fusional. Most constructions are made of bound morphemes (affixes) that must attach to a root morpheme known in Aelatha as the noun infinitive. Very few of these root morphemes can work alone, most notably are nouns in one of the possessed cases. Most roots and affixes undergo changes according to sandhi when strung together, making long compounds that are often difficult to segment or allow for multiple homonyms and homophones. Although irregularities exist, Aelatha's morphology is highly regular.
