Ndiyo, ndiyo! Also as a native Spanish speaker, I can feel confused this time... ;)
anyone know when 'siyo' is appropriate? I always used that as 'not' but I guess I might be wrong
This is for first person singular, right? Such as 'sinapenda', 'I don't like'. Or can it also be used for other things?
When used as a prefix to a verb yes it is used for the first person singular. And your example should be "sipendi" for "I don't like"
A cuban man and an african girl talk: Cuban man: Do you love me? African girl: Si! Cuban man: Mi amore! tries to do... y'know... with her African girl: Hwacha doin'? Cuban man: You said, you love me! African girl: Si means no in Swahili!
