Soporose

Soporose (SOP-uh-ros) adjective

Sleepy; in an unusually deep sleep.

[From Latin sopor (a deep sleep). Ultimately from the Indo-European root swep-
(to sleep) that is also the source of insomnia, hypnosis, and somnambulate
(to walk in sleep).]

"We have a world-class orchestra and a world-class young conductor in
Esa-Pekka Salonen. Let's develop a world-class audience to enjoy their
music. This can be done by making certain that difficult music is heard
at concerts before the old chestnuts lull the 'music lovers' into their
customary soporose state."
