What a journalist may say to make a mark? (7)
I believe the answer is:
impress
'make a mark?' is the definition.
(I've seen this before)
I don't understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for impress that I've seen before include "Stamp, emboss" , "Cut a dash" , "Make an impact" , "gain respect" , "Produce a strong, lasting impression on" .)
