Poor wager round female tumblers, etc. (9)
I believe the answer is:
glassware
'tumblers etc' is the definition.
I can't judge whether this defines the answer.
'poor wager round female' is the wordplay.
'poor' is an anagram indicator.
'round' is an insertion indicator.
'female' becomes 'lass' (lass is a kind of female).
'wager' anagrammed gives 'gware'.
'gware' going around 'lass' is 'GLASSWARE'.
Can you help me to learn more?
(Other definitions for glassware that I've seen before include "one can see through" , "Retorts, for example" , "it might be crystal" , "Vitreous items" .)
