Stand almost excessively behind catching Queen (8)
I believe the answer is:
tolerate
'stand' is the definition.
(I know that stand can be written as tolerate)
'almost excessively behind catching queen' is the wordplay.
'almost' means to remove the last letter (most of the word but not all of it).
'excessively' becomes 'too' (synonyms).
'behind' becomes 'late' (as in behind schedule).
'catching' means one lot of letters goes inside another.
'queen' becomes 'ER' (abbreviation for Elizabeth Regina).
'too' with its last letter taken away is 'to'.
'late' placed around 'er' is 'lerate'.
'to'+'lerate'='TOLERATE'
(Other definitions for tolerate that I've seen before include "Withstand" , "Be indulgent" , "Turn a blind eye to" , "Stand" , "Treat fairly" .)
