proper nouns work somewhat similarly to normal nouns; however, they don’t take ablaut. instead, they take suffixes:
they have the same suffix order as normal nouns (but with the case suffix coming first). they can also act as modifiers, attached or detached. the typical part-of-speech prefixes can be applied. however, they cannot act as verbs.
they can be changed to match fynotek phonology/phonotactics; however, this is technically not required. also, capitalization doesn't matter.
