Say sorry when logo is misprinted in copy (9)
I believe the answer is:
apologise
'say sorry' is the definition.
(I've seen this before)
'logo is misprinted in copy' is the wordplay.
'misprinted' indicates anagramming the letters (I've seen 'misprint' mean this).
'in' is an insertion indicator.
'copy' becomes 'ape' (synonyms).
'logo'+'is'='logois'
'logois' is an anagram of 'ologis'.
'ologis' placed inside 'ape' is 'APOLOGISE'.
'when' is the link.
(Other definitions for apologise that I've seen before include "Ask forgiveness" , "Say one is sorry" , "Express regret (for action)" , "Say sorry, mea culpa" , "Say sorry, my fault" .)
