There is no inflectional morphology involved with nouns anywhere. Nouns have one form only and don't inflect for case, gender or number. There are no definite or indefinite articles.
Grammatical case is expressed by word order, logic and a topic marker when necessary. In unmarked word order, the subject precedes the verb:
uma janzu
mother cook
mother is cooking
Direct objects follow the verb:
uma janzu lanki
mother cook rice
mother is cooking rice
Indirect objects can either follow or precede the direct object:
uma janzu lanki wa
mother cook rice i
mother is cooking rice for me
uma janzu wa lanki
mother cook i rice
mother is cooking rice for me
There is no separate marking for indirect objects. The difference between direct and indirect objects is left to logic and context:
yu pau wa apa
he give i money
he gave me money
*he gave me to the money
When one of the constituents is topicalized and moved to the front of the sentence thus breaking the basic unmarked SVO-order, there is the option to mark this constituent with the marker be which is placed directly after it:
lanki be uma janzu
rice top mother cook
it is rice mother cooked
*the rice cooked mother
apa be yu pau wa
money top he give i
it was money he gave to me
*the money gave him to me
There is no overt distinction between nouns with an intrinsic masculine or feminine load:
uba - father
uma - mother
wana - woman
bua - brother
The roots bu for "man" and wana for "woman" are used to make new words with this load in order to indicate the sex of a being when necessary:
ume - sheep
bume - ram
waname - ewe
These roots usually are prefixed, but sometimes they occur at the end of words too:
uva - spouse
vabu - husband
vawana - wife
Number and definiteness is derived from the context or expressed with quantifiers or deictic markers:
nia
car
the/a car/cars
nia wi
car many
many cars
nia sun
car two
two cars
nia yo
car all
all cars/every car
Collective nouns are characterized by the ending in the root nyo meaning "collection, many of". Please keep in mind this is a closed class and not a suffix which can actively be applied to nouns in order to pluralize them. Examples of words containing this root are:
unyo - people, ethnic grouping
Majaranyo - the Hungarian people
penyo - forest
jinyo - band
Some words without this root nyo have an intrinsic collective meaning and are a mass noun on their own:
aso - water
shum - grains
apa - money
Also note substances like elements in general have no separate collective form altough in many instances they do express mass nouns:
vungu - gold
ninia - helium
kwengu - silk
fangu - iron
Mass nouns too can be modified by quantifiers or other nouns in order to denote a more specific amount:
binso yem - three (glasses of) beer
seo na aso - a cup of water
simbe chu vungu - a piece of gold
