Parenthesis
A parenthesis (parenthetical expression) is a relative clause, introduced with vew (which), that modifies its head nonrestrictively. In other words, it provides additional, nonessential information about the head without defining it. If omitted, the subject of the parenthesis is implicitly the modified head.
| gɪgɪ ⟨gɪ⟩ — thedefinite determiner | vew | tir | ŋix | |||||||||||||||||||||||||
| gɪ | vew | tir | ŋix | |||||||||||||||||||||||||
| the | which | is good | dog | |||||||||||||||||||||||||
| “the dog (dogs are good)” | ||||||||||||||||||||||||||||
Here, vewtir asserts that dogs are good (it is excellent to be a dog). We could remove the non-restrictive modifier entirely, and the meaning of gɪgɪ ⟨gɪ⟩ — thedefinite determinerŋix would not change. In fact, we could split this sentence into two: tirŋixgɪgɪ ⟨gɪ⟩ — thedefinite determinerŋix.
Restricted noun phrases, such as determiner phrases and pronouns, cannot be further modified by prepositional phrases. For instance, nʊtaykwʊ (happy I) is ungrammatical. Conversely, a parenthesis can modify a restricted noun phrase.
| vew | tir | gɪgɪ ⟨gɪ⟩ — thedefinite determiner | ŋix | |||||||||||||||||||||||||
| vew | tir | gɪ | ŋix | |||||||||||||||||||||||||
| which | is good | the | dog | |||||||||||||||||||||||||
| “the dog, which is good” | ||||||||||||||||||||||||||||
In this example, vewtir does not contribute to the identification of the dog, nor does it describe dogs in general; it provides extra information about a particular dog that has already been identified.
