Significa "séquito, entorno"; se escribe igual que en francés, y justamente proviene de ese idioma a partir del verbo entourer ("rodear, cercar").
"It took quite a while, as everyone was streaming along with the slow procession of the coffin bearers and their entourage towards the King's limousines and horse-drawn coaches that waited near the palace gates (Ursula Kroeber Le Guin)"
