This paper investigates language practices, language attitudes and identity belongings of East Timorese in the Netherlands. Data were gathered through a limited orally conducted sociolinguistic questionnaire and two in-depth interviews on the sociolinguistic trajectories of our participants. The questionnaire shows that second-generation East Timorese all shifted to Dutch. Also the first generation shifted to Dutch and many in addition acquired mainly English and some Portuguese, Spanish or Polish. They did, however , not lose their home languages (mainly Tetum and Indonesian) with the exception of some regional languages (that are, however , still used on social media). Irrespective of the importance of Dutch in their day-to-day language practices, participants reported Tetum to be their most preferred and used language and the language of their East Timorese identity. The in-depth interviews show that the ensemble of linguistic resources of the East Timorese in the Netherlands constitutes the community of practice and knowledge they are part of. Their individual choices from these repertoires, irrespective of how they were acquired and irrespective of their proficiency, constitute their sociolinguistic profile. In this profile Tetum no doubt played and still plays a major role as the main language of East Timorese identity.
