Take note of second evangelist (4)
I believe the answer is:
mark
This clue might be a double definition.
'take note of' is the first definition.
(I've seen this before)
'second evangelist' is the second definition.
'mark' can be an answer for 'evangelist' (thesaurus). I'm unsure of the 'second' bit.
Can you help me to learn more?
(Other definitions for mark that I've seen before include "Starting point in race" , "Former German monetary unit" , "Note Germany currency" , "Matthew, . . . ., Luke and John" , "Stay close to one's opponent" .)
