A nomad is someone who lives by traveling from place to place. Nomadic thus means anything that involves moving around a lot. Nomadic hunter-gatherer tribes follow the animals they hunt, carrying tents with them.
Un nomade est une personne qui vit en voyageant d’un endroit à l’autre. Le nomadisme désigne donc tout ce qui implique de se déplacer beaucoup.
