Make a lasting impression? (4)

Ross

I believe the answer is:

etch

'make a lasting impression' is the definition.
(I've seen this in another clue)

This is the entire clue.

(Other definitions for etch that I've seen before include "Use acid to cut design" , "Wear away by chemical reaction" , "Engrave; fix firmly" , "Cut deeply (with acid?)" , "Draw on metal with acid" .)

I've seen this clue in The New York Times, the LA Times and The Wall Street Journal.
