The word "re nigging" is often misspelled as "reneging". The correct pronunciation of this word is /ri-nig-ing/, with stress on the second syllable. The "e" in "re" is not pronounced separately but rather carried over from the prefix "re-" meaning to do something again. Meanwhile, the "nig" in "nigging" is pronounced as /nɪg/, similar to the word "big". "Reneging" means to go back on a promise or commitment, and the word "re-nigging" would imply doing so again.
The term "re nigging" does not have an established etymology as it is considered an offensive and derogatory racial slur. However, it likely originated as a modification of the racial slur "nigger", which has a long history of usage to demean and dehumanize Black people. It is important to note that using or promoting racial slurs contributes to discrimination and should be avoided.
