Code switching
‘The switching from the linguistic system of one language or dialect to that of another. This could be matching the linguistic system of the person with whom you are conversing with as to not stand-out.’
Personal accounts
“When you speak more than one language it’s just second nature ”
“As a middle class man I often felt that I had to code switch when working on building sites. And I still ended up being called ‘professor’ or similar more often than not.”
