please explain me something : : if WADOGO and MDOGO mean the same thing, when are they to be used ? for singular and plural ?" mdogo mtoto wadogo watoto ? or didn't I understand anything until now ? thanks.
So, if you refer to 'one younger sibling (Singular), it would be mdogo, and if referring to all younger siblings (Plural), it would be wadogo.
If it starts with a 'm', doesn't that indicate person? "Kidogo" should be small
I don't think there's anything particularly (in)animate about "small" or "little" in English. Both can refer to people, animals, or objects. Also, mdogo is not just for M-/WA- nouns; it can be used with M-/MI- nouns (mti mdogo "little tree") or U-/N- nouns (ufunguo mdogo "small key").
