Russian fighter protecting name for dynasty (4)
I believe the answer is:
ming
'for dynasty' is the definition.
(Chinese dynasty)
'russian fighter protecting name' is the wordplay.
'russian fighter' becomes 'MiG' (Russian fighter plane manufacturer).
'protecting' is an insertion indicator (inserted letters are held or protected).
'name' becomes 'n' (common abbreviation e.g. on forms).
'mig' placed around 'n' is 'MING'.
(Other definitions for ming that I've seen before include "Chinese dynasty 14th-17th centuries, or porcelain" , "An imperial Chinese dynasty" , "Chinese dynasty - Flash Gordon's foe" , "Porcelain associated with Chinese dynasty" , "Chinese dynasty and Roscommon TD" .)
