Veins damaged by old saw? (9)
I believe the answer is:
envisaged
'saw?' is the definition.
(seeing is a kind of envisaging)
'veins damaged by old' is the wordplay.
'damaged' indicates an anagram.
'by' says to put letters next to each other.
'old' becomes 'aged' (similar in meaning).
'veins' with letters rearranged gives 'envis'.
'envis'+'aged'='ENVISAGED'
(Other definitions for envisaged that I've seen before include "Pictured" , "Imagined" , "Contemplated" , "anticipated" , "Fancied" .)
