Nkwu

Nkwu (endonym: tembadu hānkwu [te̞ˈmbaɾu ˈhaːŋkwu]) is a language spoken by the Nkwu people of Bū.

Phonology

Consonants

The usual phonemic analysis of Nkwu consonants devised by Trang (1958) comprises many phonemes that, on surface analysis, would appear to be clusters. These are analysed as phonemes for reasons of parsimony in describing phonotactics and morphophonology.

Vowels

Nkwu has a simple system of five-vowels qualities as in Spanish and Swahili.

Single vowels

	front	central	back
high	i		u
mid	e		o
low		a

Some authors have described Nkwu as also having phonemic long vowels as well, however long vowels behave prosodically in an identical way to vowel sequences, encouraging the analysis of them as sequences of two identical vowels. Such sequences of two identical vowels are, however, generally written with a macron for traditional reasons and to save space, however when it is impossible to type a macron, the vowel is doubled.

Phonemic Analysis	Romanised (macrons possible)	Romanised (macrons impossible)
/a/	⟨ a ⟩	⟨ a ⟩
/aa/	⟨ ā ⟩	⟨ aa ⟩
/e/	⟨ e ⟩	⟨ e ⟩
/aa/	⟨ ē ⟩	⟨ ee ⟩
/i/	⟨ i ⟩	⟨ i ⟩
/ii/	⟨ ī ⟩	⟨ ii ⟩
/o/	⟨ o ⟩	⟨ o ⟩
/oo/	⟨ ō ⟩	⟨ oo ⟩
/u/	⟨ u ⟩	⟨ u ⟩
/uu/	⟨ ū ⟩	⟨ uu ⟩

Unstressed vowels tend to be pronounced laxly as [ɪ ɛ ɐ ɔ ʊ] for /i e a o u/. Some speakers pronounce stressed vowels more tensely, closer to their cardinal pronunciations of [i e a o u].

Morphology

The morphology of Nkwu is agglutinative, with syntactic relationships within a sentence marked by prefixes and lexical derivation achieved by prefixes, infixes and suffixes on bases.

Words are built on a root morpheme called a base. Bases are neither inherently nominal nor verbal and can be used freely with either kind of morphology with no change in meaning.

Personal Markers

The first element added to both nominally and verbally inflected words is the personal marker. These provide pronominal information about grammatical person, definiteness, specificity and rank, an inflectional dimension that will be further explained below.

Personal markers may be divided up into simple and compound markers. Simple markers are only used for singular referents in the first and second persons. In the 3rd person, personal markers do not give information about number. This means that n- and w- explicitly mean "I" and singular "you" respectively and cannot be used for "we" or plural "you", whereas l-, a third person marker, could be used for either a singular referent ("he", "she" or "it") or plural referents ("they").

Simple (singular) Personal Markers

Prefix	Person	Rank	Definiteness	Specificity
n-	1st	-	definite	specific
w-	2nd	-	definite	specific
dj-	3rd	A: "noble"	definite	specific
j-	3rd	B: "dominant"	definite	specific
d-	3rd	B: "intermediate"	definite	specific
l-	3rd	C: "subordinate"	definite	specific
t-	3rd	D: "inanimate"	definite	specific
ng-	3rd	-	indefinite	specific
h-	3rd	-	indefinite	non-specific

First and second person plurals are indicated essentially by combination of two simple markers. For example, the inclusive first person plural "we (including you)" is formed by combining the first person marker n- with the second person marker w-, producing nw-. Exclusive first person plurals, "we (not including you)" are formed by combining the n- of the first person with the definite third person marker of the appropriate rank, for example nj- means "we" in the sense of "he/they (dominant) and I". Second person plurals are similarly formed, with the exclusive 2nd person marker vw- used only for cases when every member of the group referred to is being addressed. Additional members of the group being referred to who are not being addressed will be indicated instead with a combination involving the appropriately ranked third person definite marker, such as dw- "you and he/they".

Compound (Plural) Personal Markers

Simple Prefix	Gloss	+ 1st Person	Gloss	+ 2nd Person	Gloss
n-	1-	-	-	nw-	1+2-
w-	2-	nw-	1+2	vw-	2+2-
dj-	3A-	ndj-	1+3A-	djw-	3A+2-
j-	3B-	nj-	1+3B-	jw-	3B+2-

l-	3D-	nl-	1+3D-	lw-	3D+2-
t-	3E-	nt-	1+3E-	tw-	3E+2-

Rank

Third person definite referents are assigned a rank any time they are referred to.
