Old Badanni

General Info
Old Badanni is the oldest attested stage of Badanni, the ancestor of the numerous Badasi languages; it is fairly decently documented, though not quite well enough to give a detailed and in-depth overview of every feature of the language.

Verb Morphology
Old Badanni had a peculiar and complex anomaly in its verb system — its verbs exist in two forms, based on whether they take preverbs or not. All verbs come in two pairs: one prototropic and one deuterotropic verb make up a pair. These pairs may be considered as alternating — sometimes regular, sometimes irregular or suppletive — stems, though many carry divergent semantics.

Syntax
Old Badanni was a verb-initial but head-final language — this apparent contradiction seems to have come from its shift from a vaguely verb-final order as its verb system developed to the point where, to preserve its pecularities, the verb needed to be fronted before other arguments.
