E.g. caviar dressing queens sent back? One may get cross (5)
I believe the answer is:
error
'sent back? one may get cross' is the definition.
I can't judge whether this definition defines the answer.
'e g caviar dressing queens' is the wordplay.
'g caviar' becomes 'or' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'dressing' indicates putting letters inside (inserted letters are dressed or clad in others).
'queens' becomes 'rr' (two R's - R means queen as in Elizabeth Regina).
'e'+'or'='eor'
'eor' going around 'rr' is 'ERROR'.
Can you help me to learn more?
(Other definitions for error that I've seen before include "Slip, mistake" , "Mistake from terrorist" , "Faulty judgement" , "Faux pas" , "Mistake, lapse" .)
