Homonym: Affectation (Pretension)
Affectation refers to a deliberate display of behavior, speech, or mannerisms that are not genuine or natural. People may adopt these traits to create a certain impression or to fit in with a particular social group. This can include using an exaggerated accent, adopting specific fashion styles, or mimicking the interests of others.
Often seen in social settings, affectation can be perceived as insincerity or pretentiousness. It may arise from a desire for acceptance or to project a certain image, but it can lead to misunderstandings and a lack of authentic connections with others.
