Grammar & Word origin

au sein de is a fixed prepositional phrase.

  • au is the contraction of à + le: “in/at the”
  • sein originally means “bosom,” “breast,” or “inner part”
  • de introduces the group, place, or entity concerned

The expression is followed by a noun:

  • au sein de l’équipe — within the team
  • au sein d’une organisation — within an organization

The phrase changes form before feminine or plural nouns because of the article:

  • au sein de la société — within society
  • au sein des institutions — within institutions
  • au sein d’un groupe — within a group

The noun sein can also have a literal anatomical meaning, but in au sein de, it is generally used figuratively to express inclusion or interiority.
