Saint, disturbed at Magi revealing marks on his body? (8)
I believe the answer is:
stigmata
'marks on his body?' is the definition.
'stigmata' can be an answer for 'marks' (plural of stigma - stigma can mean a mark or wound). I am not certain of the 'on his body?' bit.
'saint disturbed at magi' is the wordplay.
'saint' becomes 'st' (abbreviation).
'disturbed' indicates anagramming the letters (the order of letters is disturbed).
'at'+'magi'='atmagi'
'atmagi' with letters rearranged gives 'igmata'.
'st'+'igmata'='STIGMATA'
'revealing' acts as a link.
Can you help me to learn more?
(Other definitions for stigmata that I've seen before include "Mercian king who built dyke" , "Marks corresponding to the wounds on Christ's body" , "Christ's marks of crucifixion" , "Spots" , "that oddly makes impression on Francis" .)
