I think drekley and kivers are simply modified pronounciations of 'directly' and 'covers'. I suspect that nus is a modified pronounciation of 'nurse'. I do not have a clue about yaggering.

Maybe some of you can help with the origin or any of these words. I was born and raised in S.E Ky and grew up hearing this words daily in the context I offered.1. yaggering- ?arguing, loud boisterous; My grandmother yelling at us "you kids stop that yaggering now"2. nus or nussin- My grandmother hands me my baby sister (I was 7) "here, nus this baby while I go out to the kitchen""nurse" in the sense of "(at)tend to" not "breastfeed"3. drekley- Was used I'll be back drekely, I thought it meant later but as an adult I believe it was meant to be directly."directly"4. kivers- Grand father used to call covers."covers"Not sure about "yaggering" but the others are just words spoken with a particular accent. I like this question because the words sound like some people I know and when I read "nuss" especially it is in their voices.
I found this from the Dictionary of American Regional English- but still NOT the ORIGIN of the word
