Ladies sped off and caused annoyance (10)
I believe the answer is:
displeased
'caused annoyance' is the definition.
Although both the answer and definition are past participle verbs, I can't understand how one could define the other.
'ladies sped off' is the wordplay.
'off' indicates anagramming the letters.
'ladies'+'sped'='ladiessped'
'ladiessped' with letters rearranged gives 'DISPLEASED'.
'and' is the link.
Can you help me to learn more?
(Other definitions for displeased that I've seen before include "Upset" , "Angry" , "Furious" , "Not happy" .)
