This study explores languaging practices among plurilingual Mozambican youth based on metalinguistic discourse and considering changes in the linguistic ecology fueled by the expansion of Portuguese and other social processes in Mozambique during post-independence. Additionally, this paper discusses the hypothesis of transforming languaging practices among plurilingual youth, which through a translanguaging lens can be seen as translanguaging space (GARCÍA; WEI, 2014; WEI, 2011). The approach is multimethodological and consists of autobiographic interviews, observations and metalinguistic discourse including audio and video material. The nine participants come from two different provinces in Mozambique: Nampula and Maputo. The results confirm the emergence of new languaging practices which the youth prefer and use in communication with peers. The creativity and criticality highlighted by Wei as key elements of translanguaging space (WEI, 2011) are observed and regarded as space construction (LEFEBVRE, 1991), or revindication of space(s) and, among other things, the historical and cultural hegemonic positioning of the monoglossic ideology of Portuguese in institutional spaces.
