Nepotism
ˈnɛpəˌtɪzəm
noun
the practice among those with power or influence of favoring relatives or friends, especially by giving them jobs
Nepotism comes from the Italian word 'nipote', meaning nephew. It refers to the favoritism shown to family members, usually in granting jobs or employment opportunities, rather than based on merit or qualification.
