## Causative Prefix "pa-"
The causative prefix "pa-" indicates an object or material's utilitarian designation or purpose. In the example:
- *Panegas*: `pa-` (causative-infinitive prefix) + `-n-` (replacing "t" in "tegas") + `tegas` (log) = pillar or post\
The prefix "pa-" highlights the object's intended use or function, indicating a causal relationship between the object and its purpose. ———
## Morphological Process: Nasal Substitution
The replacement of the first-letter "t" with "n" in Boie'nen words, as seen in examples like "panegas" (pa- + -n- + tegas), "panapas" (pa- + -n- + tapas), and "panigbas" (pa- + -n- + tigbas), is an instance of *nasal substitution*.
Nasal substitution is a morphological process where a nasal consonant (like "n" or "m") replaces or is inserted in place of another consonant, often to indicate a specific grammatical function or to form a particular type of word.
In Boie'nen, this process appears to be a consistent pattern when forming words with the causative-infinitive prefix "pa-", where the initial consonant of the root word is replaced with a nasal consonant "n". —-———-
Additional examples:
pamotos (pa- + -m- [-p- replacement of “potos” or wrap] + potos): wrapper/for wrapping
pamotnay (pa- + -m- [-p- replacement of ”potnay” or lie/untruthful] + potnay ): habitually lie / keeps telling lie
pamoro (pa- + -m- [-p- replacement of “poro” or tip/end): something attached or worked on at the end of the process or product
