A corpus-based sociolinguistic study of could you and would you in contemporary British English

Abstract Despite the significant role of politeness markers in managing interpersonal communication, relatively little attention has been paid to the modal forms could you and would you , particularly regarding their functional differences and sociolinguistic variation. This corpus-based study investigates these two politeness markers in contemporary British English using data from the Spoken British National Corpus 2014, a large collection of conversational British English across regions and social groups. Furthermore, the study examines how social variables (gender, age, and social class) influence the use of these expressions. The findings reveal significant functional differences between the two markers: could you is often used for checking possibilities, while would you is more commonly employed for making suggestions or offering something. Gender was found to have little impact on the use of could you , whereas would you was more frequently used by females. Age and social class also showed variation in the use of these markers, with younger speakers preferring could you for seeking information and middle-aged individuals using would you for making requests. This study contributes to the understanding of how politeness strategies vary across social contexts, offering new insights into how linguistic markers serve as tools for social negotiation and interpersonal communication.
