She took an order during the sale (6)
I believe the answer is:
salome
'she' is the definition.
'order during the sale' is the wordplay.
'order' becomes 'om' (Order of Merit).
'during' indicates putting letters inside.
'om' placed within 'sale' is 'SALOME'.
'took an' acts as a link.
I am not very happy about this link. Some or all of it may belong to another bit of the clue.
Can you help me to learn more?
(Other definitions for salome that I've seen before include "She demanded head of John the Baptist" , "13 dn for Herod" , "Biblical dancer" , "18 [OPERA]" , "She danced famously for Herod" .)
