Synonym discussion
Sense: noun/2
All three words describe unfair treatment, but they differ in scope and context. 'Bias' is the broadest — it can refer to unconscious prejudice or a statistical tendency, not just deliberate favouring ('the study found a gender bias in hiring'). 'Nepotism' is the narrowest: favouritism specifically toward family members in a professional context ('the company was run on nepotism, with cousins in every department'). 'Partiality' is more formal and often appears in legal or philosophical writing about fairness ('a judge must avoid any appearance of partiality'). 'Favoritism' sits between them — it covers any personal preference that overrides merit, whether the recipient is a relative, a friend, or simply someone the authority figure likes.
Common collocations
Etymology
Derived from the noun 'favor' (from Latin 'favor', meaning 'goodwill, kindness'), combined with the suffix '-ite' (indicating a person who is preferred or beloved) and further with '-ism' (forming a noun for a practice or system). The word entered English in the 18th century through French 'favoritisme'. The concept — giving preferred treatment based on personal relationships rather than merit — has remained stable across centuries.
