Latin Elephant is a London-based charity that works with migrant and ethnic groups in processes of urban change, and which has had a critical role in articulating the voices of traders threatened by displacement in the context of the Elephant and Castle redevelopment plans over the last decade. In this Lexicon Conversation, members of Latin Elephant discuss with RHJ the different ways in which language, vocabularies, solidarity, memory and translation have played out in their work in South London, both in relation to the use of English vis-a-vis other native languages, but also in terms of the technical language of planning in relation to intersectional urban struggles on the ground.
