The third generation of immigrants in Britain occupies a distinctive position in cultural and psychiatric discourse. Born and raised in the UK, they embody Britishness in language, education and socialisation, yet may still encounter symbolic boundaries of belonging. This paper examines third-generation experience through cultural psychiatry, highlighting hybridity, identity negotiation and the intergenerational transmission of memory and trauma. It outlines the sociological and clinical implications of these dynamics, arguing that psychiatric assessment and formulation must attend to cultural and structural contexts to understand distress and resilience. Greater attention to these processes may support more meaningful engagement and more ethically grounded clinical care.
