Have concern about physical contact in cast ornamental tablet (9)
I believe the answer is:
cartouche
'ornamental tablet' is the definition.
(I've seen this before)
'have concern about' is the wordplay.
'have' becomes 'touch' (touching is a kind of having).
'concern' becomes 'care' (synonyms).
'about' is an insertion indicator.
'touch' put within 'care' is 'CARTOUCHE'.
'physical contact in cast' is the link.
This may not be right. Some or all of it may belong to another bit of the clue.
Can you help me to learn more?
(Other definitions for cartouche that I've seen before include "Ornate frame around an inscription" , "Oval around the hieroglyphic name of a pharaoh" , "case of bullets" , "decorative ornament" , "Tablet in scroll form" .)
