 • The Pendent Case introduces a noun phrase without stating any relation between it and the current clause, and binds it to the Pendent pronoun (whose root form is ⟪-ƛá⟫ and whose extensional form is ⟪-ƛ◈-⟫, with ⟪◈⟫ representing an Inner Case vowel). This allows the introduced noun phrase (now bound to the pendent pronoun) to be used latter, possibly in a subordinate clause not yet opened. This is especially useful for expressing quantification binding a variable that is not used in the same clause as the one in which the quantifier appears, but rather in a more deeply nested clause:

 # Other case-like roles
 
 These Role prefixes (Slot 2a) behave much like noun cases, although the syntactic roles they govern aren't nominal; like noun cases, they are accompanied by an Inner Case vocalic affix, and an optional Determinacy affix.

 • The Plural Union Case has a special syntax: instead of complementing the clause's verb, it links together the marked noun and the immediately preceding one, merging them into a single new noun whose referents are the union of the referents of the two target nouns; this corresponds to certain usages of the word ⟪and⟫ and the expression ⟪together with⟫ in English.  
   The two following example sentences illustrate the difference between the ‘logical AND’ and the plural union:

 • The Propositional Case turns the contentive word into a restrictive subordinating clausal adverb, i.e. an adverb that modifies the whole proposition represented by the current clause, and not describing the physical spatiotemporal manifestation (event) of that proposition: it would be suitable for expressing the adverbs "probably", "arguably", "frequently", but not event-specific adverbs such as "beautifully", for which the Eventive Case would be appropriate.
