Noun and noun or noun

I just finished designing Tunu nominal forms. Below are examples :

mara : big
memara : small
momara : size
(memara oti kana : i am small)

miki : house
mamiki : village
mumiki : House = home
(mumiki ono kana : I dwell in)

tunu : word
tatunu : sentence
tutunu : Word = language
(tutunu oko kana : i speak)

natu : hot season
nenatu : cold season
nonatu : both hot and cold seasons = year
ninatu : a season

tike : finger
tatike : hand
tetatike : the other hand
totatike : both hands
titatike : a/the hand

How do your conlangs deal with definite, abstract, collective, etc. nouns ?
