Annoyed thief on a boat losing power (5)
I believe the answer is:
irate
'annoyed' is the definition.
(I've seen this before)
'thief on a boat losing power' is the wordplay.
I cannot quite see how this works, but
'on' could be 'at' (I've seen this in other clues) and 'at' is present in the answer.
'boat' could be 'e' and 'e' is present in the answer.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for irate that I've seen before include "Annoyed, irritated" , "Aggrieved" , "Narked" , "Angry, enraged" , "Full of 22" .)
