Evangelist making an impression (4)
I believe the answer is:
mark
This clue is a double definition.
'evangelist' is the first definition.
(traditional author of the Gospel of Mark)
'an impression' is the second definition.
(I know that mark is a type of impression)
'making' is the link.
(Other definitions for mark that I've seen before include "Characteristic" , "Scar; note" , "Spot - score - note - boy's name" , "Note Germany currency" , "Brand - old German currency" .)
