What here make funguo plural "keys" not "key"? Or does swahili not distinguish between this group of people wanting 1 key or multiple?
The singular is "ufunguo" and the plural is "funguo". The z in "zao" also indicates that keys is plural.
When does one use Wao and Zao?
wao is for the singular (Ufunguo) and zao indicates plural (Funguo)
Why does it not accept "require"? Is there a differences?
They probably just didn't add it. Require is essentially just a more formal way of saying need.
