Queen replacing theatre in time for procession (8)
I believe the answer is:
sequence
'for procession' is the definition.
(thesaurus)
'queen replacing theatre in' is the wordplay.
'replacing' indicates an anagram (placing again).
'theatre' becomes 'sce' (I can't explain this - if you can you should give a lot more credence to this answer).
'in' is an insertion indicator.
'queen' is an anagram of 'equen'.
'equen' put inside 'sce' is 'SEQUENCE'.
'time' acts as a link.
I am not very happy about this link. It may belong to another bit of the clue.
Can you help me to learn more?
(Other definitions for sequence that I've seen before include "Ordered series" , "26 [ORDER]" , "Series of things in order" , "The following of one thing after another in orderly way" , "Arrangement of things in order" .)
