After 2, sweetheart meets Insurer, with bit of ancient earthenware (8)
I believe the answer is:
majolica
'earthenware' is the definition.
(majolica is a kind of earthenware)
'after 2 sweetheart meets insurer with bit of ancient' is the wordplay.
I cannot quite understand how this works, but
'sweetheart' could be 'jo' (Scottish term for darling or sweetheart) and 'jo' is located in the answer.
'bit' could be 'i' (resembles 1, a binary digit or bit) and 'i' is present in the answer.
This may be the basis of clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for majolica that I've seen before include "Highly-decorated style of earthenware (J, not I)" , "Type of highly-decorated glazed earthenware" , "Glazed porous pottery" , "Pots" , "Highly decorated glazed earthenware" .)
