Regard in false earrings (3)
I believe the answer is:
see
'regard' is the definition.
(I know that regard can be written as see)
'in false earrings' is the wordplay.
'in' indicates a hidden word.
'SEE' is hidden in the letters of 'false earrings'.
(Other definitions for see that I've seen before include "District of a bishop - or Pope" , "Bishop's responsibility; observe" , "Chelmsford" , "Salisbury, for one" , "View; realise" .)
