The least Common case for nouns, due to its rigorous requirements. Despite the name, it is NOT used when the noun is an object (you leave it in the normal case).
Save in special cases, it is only used when it is the initial, non-verb piece of a compound with a verb.
Special Case:
A special case concerns crafting a name with a clear Masculine/Feminine gender. The initial noun/adjective can be put into the respective gendered inflection to improve the flow and strength of the name. If the initial word is triconsonantal and full form, it undergoes Syncope.
Example: bawab + thôr à bawbuthôr, “Wind-son.” Feminine equivalent would be bawab + phêl à bawbiphêl, “Wind-daughter.”
(Strong-I/Strong-II) Neuter, Common, Feminine, and Masculine: change variable noun to -u.[1]
Example(s):
Azra > Azru (e.g. azrubêl, “sea-lover, friend of the sea”).
Raba > rabu (e.g. rabubât, “dog-walker”)
Lômi > lômu (e.g. Lômuzîr, “lover of the night filled with stars”)
Khibil > khiblu (e.g. Khiblugunôd, “spring digger/digger of springs”)
(Weak-I/Weak-II) Neuter, Common, Feminine, and Masculine: add -u to the end (vowel-combinations apply).
Example(s):
Rabê > rabêu (e.g. rabêuzûr, “bitch (female dog) caretaker”)
Bêth > bêthu (e.g. Bêthudûk, “word-dweller”)
[1]. Feminine nouns can also use -i instead.
