From a discursive perspective, concepts like ‘migration’ and ‘mobility’ are not self-evident, descriptive or apolitical phenomena but are politicized in various ways on different governmental levels. While European member-states mainly refer to ‘migrants’ and their ‘integration’, European institutions mainly refer to the importance of ‘European mobility’ for ‘mobile workers’ and the ‘Single market’. As such, migration and mobility are by no means neutral, descriptive or obvious phenomena. Instead, ‘migration’ and ‘mobility’ can be seen as non-self-evident, politicized and contested concepts, which is also more and more acknowledged in the literature. Such insights demands more political sensitivity in the scholarly usage of ‘migration’ and ‘mobility’ grammar.
