Sidotullian

Sidotullian is a term commonly used in science fiction and worldbuilding to designate the inhabitants of the fictional planet Sidotulla and their language. The term can refer to people, the language, or both, depending on the source.

Etymology: The name Sidotullian derives from the planet Sidotulla, with the suffix -ian indicating belonging or affiliation, a convention parallel to real-world demonyms and language names.

Geography and society: In most depictions, Sidotullians inhabit a cluster of coastal city-states around Sidotulla's equatorial belt. They are portrayed as maritime traders and skilled engineers, organized into guilds and councils. Education and public life emphasize navigation, astronomy, and architecture.

Language: Sidotullian refers to the language or languages spoken by Sidotullians. It is typically described as agglutinative or polysynthetic, with a flexible sentence order and a rich system of evidentiality and honorifics. Script varies, with some texts using a mixed logographic-alphabetic system and others in pure alphabetic scripts. In-world scholars describe substantial dialect diversification aligned with geographic regions and city-states.

History and reception: In fictional chronicles, Sidotullians undergo periods of growth, conflict, and cultural exchange with neighboring civilizations, leading to widespread linguistic borrowing and script reform. The topic remains popular in worldbuilding circles for illustrating maritime civilizations and language contact.
