Politeness theory is an academic framework within linguistic pragmatics and sociolinguistics that models how language users employ communicative strategies to maintain social harmony and manage interpersonal relationships, particularly concerning the concept of 'face'. It investigates the motivations, types, and effects of polite language use, analyzing how individuals mitigate potential social friction arising from 'face-threatening acts' through various linguistic choices, thereby offering crucial insights into the social dynamics of verbal interaction.
