Make an engraving (4)
I believe the answer is:
etch
'make an engraving' 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 "Carve (design) on a surface" , "Score deeply" , "Make a deep impression" , "Cut lines with acid" , "Cut into a block used for printing" .)
