Presubject

Presubject elements may be conjunctions, prepositional groups, nonfinite clauses, or whole dependent clauses that precede the grammatical subject of the main clause.

Tense/aspect/mood (tam) particles furnish a broad range of conjugation patterns (i.e. patterns in which verb stem can appear) and can be subdivided into two positional classes of preverbal and presubject particles.

These may occur in presubject position, prepredicate position, within the verb phrase, preceding equated attributives, and final to the clause.
