Turkish Cypriot language is a minority language spoken by the Turkish Cypriot community in London. Like any other minority language, Turkish Cypriot, the minority language, is being influenced by English, the majority language, and therefore the code-switching behavior inevitably occurs and increases over generations. We; bilingual Turkish Cypriots code-switch with any other Turkish English bilingual consciously or unconsciously, almost anywhere. Bilinguality covers a huge part of our lives.. we feel incomplete , we can not express ourselves fully without the help of two languages combined together. Having spent years in London Turkish Cypriot Londoners code-switch for many reasons; solidarity, secret messaging ... etc.. But does it always have a reason ! ? Sometimes yes sometimes no ! But it is certain that a bilingual Turkish English conversation is much more meaningful, funny, witty and comprehensible then a monolingual conversation to bilinguals. In this research study we canobserve varied levels of code-switching behaviours by different ages and sexes at different contexts and settings. And see if it s a yes or a no .
