Sycophant
ˈsɪk.ə.fənt
noun
a person who acts obsequiously towards someone important in order to gain advantage
The word 'sycophant' comes from the Greek word 'sykophantēs,' which originally referred to informers or slanderers in ancient Athens. Over time, it evolved to denote individuals who flatter or behave subserviently to gain favor or advantage.
See how Walt Whitman and James Joyce use "sycophant", with its meaning, pronunciation and real book examples.
