Anxiety caused when tipsy butler steals ring... (7)
I believe the answer is:
trouble
'anxiety' is the definition.
(I know that trouble is a type of anxiety)
'tipsy butler steals ring' is the wordplay.
'tipsy' indicates an anagram.
'steals' means one lot of letters goes inside another.
'ring' becomes 'O' (letter resembling a ring).
'butler' anagrammed gives 'truble'.
'truble' going around 'o' is 'TROUBLE'.
'caused when' acts as a link.
(Other definitions for trouble that I've seen before include "Hassle" , "Distress - concern - effort" , "Difficulty or inconvenience" , "Pains" , "Nuisance, bother" .)
