Wept about queen getting an alloy (6)
I believe the answer is:
pewter
'an alloy' is the definition.
(pewter is a kind of alloy)
'wept about queen getting' is the wordplay.
'about' indicates anagramming the letters.
'queen' becomes 'er' (abbreviation for Elizabeth Regina).
'getting' says to put letters next to each other.
'wept' anagrammed gives 'pewt'.
'pewt'+'er'='PEWTER'
(Other definitions for pewter that I've seen before include "Grey alloy of tin and lead, makes mugs etc." , "Tin alloy used in tankards, etc" , "Plate" , "prize-money" , "Alloy mainly of tin and lead" .)
