What sorceress might do with burning ship (10)
I believe the answer is:
witchcraft
'what sorceress might do' is the definition.
(sorceress can mean a witch)
'with burning ship' is the wordplay.
'with' becomes 'w' (abbreviation).
'burning' becomes 'itch' (both can mean a strong desire).
'ship' becomes 'craft' (I've seen this in another clue).
'w'+'itch'+'craft'='WITCHCRAFT'
(Other definitions for witchcraft that I've seen before include "Supernatural power" , "Magic" , "broomstick?" , "Frank Sinatra single" , "[OBI], say" .)
