Etching has engineer delirious (9)
I believe the answer is:
engraving
'etching' is the definition.
(synonyms)
'engineer delirious' is the wordplay.
'engineer' becomes 'eng' (abbreviation).
'delirious' becomes 'raving' (I've seen this in another clue).
'eng'+'raving'='ENGRAVING'
'has' is the link.
(Other definitions for engraving that I've seen before include "art" , "Carving on hard surface" , "Print" , "Cutting" , "the funeral ceremony?" .)
