Eridanian, [ɛɹɪdænɪjən] (Natively Rdaanssboox, [ʁdaːnsspoːx]), is an Anglic language spoken on Epsilon Eridani III in the year AD 4000, one of many languages that evolved from English. It is a synthetic language with a rich morphology of prefixes derived from English prepositions, articles, axillary verbs, modals, and other grammatical particles and constructions.


In 2389 several hundred thousand Americans and Canadians from around the Great Lakes region fled an increasingly totalitarian Terran Federation government to a nearby Earth-like planet that was as yet unsettled, Epsilon Eridani III, about 10 light-years from Earth. When the Federation collapsed in the early 2500's the infrastructure that allowed for interstellar travel collapsed, resulting in a period later generations would call a "dark age" reminiscent of the one following the fall of Rome. The various interstellar colonies, including E. Eridani III, which came to be called Eridanus, later Rdaans, were cut off from the Solar System and on their own. The various dialects of spoken English, which were already quite different from the written language, "Classical English", began thier divergence into separate languages.

Stress and ProsodyEdit

Eridanian is a stress-timed language with primary stress located on the first syllable of the root. It also has a pitch accent derived from the elision of consonants. Some roots and morphemes are only distinguished by having a rising, falling, or level pitch.

Verbal MorphologyEdit

Eridanian verbs are agglutinative in structure and inflect for Tense, Aspect, Mood, Voice, and for the person and number or the subject and direct object. Some affixes have various forms marking for number and person, preserving their origin as English's axillary verbs and modal particles.

Personal EndingsEdit

The number and person of both the subject and direct object are marked on the verb with affixes derived from pronouns. The 3rd Person Singular distinguishes between animate and inanimate nouns.

Tense and AspectEdit

Eridanian has 5 tenses, Present, Past, Future, Present Conditional and Past Conditional; but preserves many elements of the old Germanic Past/Non-Past system, especially in the conjugation of "to be" and the use of the affix "-on" to mark the future tense, a relic of the modern spoken English periphrastic "be + gonna" Future construction (the old "will/shall" periphrastic Future is gone with little trace).The Present conditional is derived from "can". The Past Conditional is formed from the English "was gonna" Future-in-the-Past.

Eridanian marks for Perfect and Progressive aspects and retains the odd semantics of English's Present Progressive and Simple Present in active verbs.

Eridanian has 6 moods, Indicative, Subjunctive, Optative, Imperative, Obligative and Interrogative. The old Germanic Subjunctive is preserved only in the verb "to be", the result of it stubbornly refusing to disappear in American English. A new Subjunctive formed from "should" becoming attached to the subject inflections. The Interrogative Mood is the result of interrogative pronouns fusing to the verb and occur in the place of the normal subject inflections. The imperative marker is derived from "let's
Subjunctive: shwou-vo-syaabn = If I were stopping
Obligative: ou-gaa-syaaf = I must stop/I got to stop
Optative: ou-waan-syaaf = "I want to stop/I would like to stop
Interrogative (Animate): hou-s-syaabn = Who is stopping?
Interrogative (Inanimate): wa'-s-syaabn = What is stopping?
Imperative: las-syahf! = STOP!


Eridanian has 3 morphological voices, Active, Passive, and Reflexive. The Passive Voice is derived from the English "got + Past Particple" construction. The Reflexive Voice originated from the fusion of the reflexive pronouns onto the verb.
Passive: e-go'-shaaft = "I was stopped"
Reflexive: mousu-shaaf = "(I) stop myself"

Verbal derivationEdit

Verbal derivational affixes are placed before the verb root.

Inchoative: -syau'-
Causative: -mea-
Continuative: -syiu-
Cessative: -ki'-
Resumptive: -kyon-

Infinitive, Gerund, and Participle formsEdit

Infinitive: t(a)-ROOT
Gerund: ROOT-ag
Present Participle: ROOT-n
Past Participle: Identical to the Simple Past form of the verb except for a few strong verbs.


Eridanian is nominally a SVO language, but has many VSO elements as well. Informal conversations tends more towards verb-first placement. The verb is always at the start of the sentence in polar ("Yes-No") questions, but the Subject is always first when it is the emphasized or topical point of the sentence. Adpositions are always prepositional, located at the start of the adpositional noun phrase. Adjectives follow nouns.
