NEPOTISM

n. granting of favors to relatives; favoritism shown to relatives (especially in securing jobs)

Nepotism is the showing of favoritism toward relatives, based upon that relationship, rather than on an objective evaluation of ability or suitability. For instance, offering employment to a relative, despite the fact that there are others who are better qualified and willing to perform the job, would be considered a form of nepotism. The word nepotism is from the Latin word 'nepos', meaning "nephew" or "grandchild".
