Gets fed up with complicated rites (5)
I believe the answer is:
tires
'gets fed up' is the definition.
I can't tell whether this defines the answer.
'complicated rites' is the wordplay.
'complicated' is an anagram indicator.
'rites' with letters rearranged gives 'TIRES'.
'with' is the link.
Can you help me to learn more?
(Other definitions for tires that I've seen before include "Weakens" , "Grows weary of rites" , "Wearies" , "Exhausts" , "Becomes weary and in need of rest" .)
