Crossword Genius

Ornament to corrode (4)

Ross

I believe the answer is:

fret

This clue is a double definition.

'ornament' is the first definition.
(fretting is a kind of ornamenting)

'corrode' is the second definition.
(fretting is a kind of corroding)

'to' acts as a link.

(Other definitions for fret that I've seen before include "Worry - ridge on guitar's fingerboard" , "Worry unnecessarily" , "coastal mist" , "Split up" , "Worry; or the marking on a guitar" .)

I've seen this clue in The Telegraph.
