To say "little house" in an African language, you would need to use two words: one for "little" and one for "house."
Here are some examples:
* Swahili: Nyumba ndogo (nyumba = house, ndogo = small)
* Yoruba: Ile kekere (ile = house, kekere = small)
* Zulu: Indlu encane (indlu = house, encane = small)
* Amharic: Bet kecil (bet = house, kecil = small)
You will need to specify which African language you're interested in to get a more accurate translation.
