Tanðab

Tanðab is a descendant language of Sajem Tan created by Žirik (Fish), whose name, in Tanðab, is rendered as Jijik. Specifically, it is a pidgin or creole of Skype Tan with the semi-canonical Dab Vi Suxi Kidap (DVSK), a minimal language created as a side project by Bird, Fish, Wind, Fern, and Fog, though Fish eventually became the last one working on it.

Tanðab has phonology and grammar mostly derived from DVSK, and vocabulary mostly derived from Sajem Tan, with some DVSK words included, especially for common words or words for which the original Sajem Tan roots have merged in confusing ways due to sound changes. Tanðab diverged from Skype Tan before its contact with Xanz and other languages, and thus lacks such features as triconsonantal roots.

Grammar
Tanðab grammar is rather simple. Main clauses can be either SOV or OVS. Pro-dropping is the default, with subject pronouns only being used emphatically or contrastively, so many statements consist of only OV.

Nominal Phrases
The nominative case is marked by -buk and the direct case, corresponding to Sajem Tan's accusative and other unmarked cases, by -ðab. Skype Tan's system of lexical gender is entirely lost, and a new system of noun classes is derived phonetically.

Verb Phrases
Modal and aspect-like auxiliary verbs are rebracketed as suffixes/clitics but are not otherwise changed significantly. Other auxiliary verbs either become particles, regular verbs, or are lost and replaced by other grammar.

Tense
Due to sound changes, the near and far past forms of ö-auxiliaries merge, resulting in the Skype Tan far past disappearing from Tanðab; the mid-past forms take their place. Thus, Tanðab has three tenses, non-past, near past, and far past.

Aspect
Aspects are largely similar to Sajem Tan, except that -da (corresponding to an archaic form of ST perfective) is the regular perfective aspect and -fe (corresponding to the modern ST perfective) is the momentane aspect, while -ub (modern ST gnomic) is the continuous aspect and -xo (modern ST continuous) is the progressive aspect. The other imperfective aspect, -et (modern ST habitual) is the frequentative aspect.

Perfective Aspect
The perfective aspect, -da, describes any event or action in its entirety, as a single piece without internal structure. In the past tense, -da directly contrasts with the momentane aspect, which describes very brief events, otherwise, it does not imply anything about the actual length of time the event or action took.

Momentane Aspect
The momentane aspect, -fe, describes an event which is short-lived, particularly one which is sudden and without build-up. It is only used in the past tense, where it contrasts with -da.

Continuous Aspect
The continuous aspect, -ub, describes states of being. These are often permanent, but need not be; any verb which describes a continuous, static-for-the-duration state is covered by -ub.

Progressive Aspect
The progressive aspect, -xo, describes continuous extended actions. These involve some kind of change or activity over the course of the action, but describes only a single action, not a pattern of them.

Frequentative Aspect
The frequentative aspect, -et, describes repeated actions. This is very similar to the habitual aspect of Sajem Tan and many other languages, but the name is changed to clarify the distinction between progressive, continuous, and frequentative. Specifically, iterative actions (which happen repeatedly according to a rule, such as at regular time intervals), and not just strictly habitual ones (which have a tendency to repeat or repeat based on the choices of agents) are frequentative, and not continuous or progressive.
