Not being Nigerian, I was unaware that it was commonplace to end sentences with "now." But, being eager to learn, it's something that I know about, "now." Is there a reason that sentences are frequently ended with the word "now?" Having had it pointed out to me, I'll be more aware of it, "now." And, if I do it when speaking, will I sound more like a native, "now?"

the word is not really now but na,

"na" sometimes represents anger or plead.

example, please talk to me na.(plead)

what is wrong with you na.(anger)

Oh, I see.   I'm sorry.
