Stars displeased -- daughter missing -- becoming agitated (8)
I believe the answer is:
pleiades
'stars' is the definition.
(I've seen this before)
I cannot understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for pleiades that I've seen before include "night-time sight" , "Star cluster representing sisters in mythology" , "Conspicuous star cluster in Taurus" , "Group of sisters" , "Prominent star group" .)
