Verity, a model Moabite woman (5)
I believe the answer is:
truth
'verity' is the definition.
(synonyms)
'a model moabite woman' is the wordplay.
I cannot quite understand how this works, but
'model' could be 't' (Ford Model T car) and 't' is found in the answer.
'woman' could be 'ruth' and 'ruth' is found in the answer.
No letters remain.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for truth that I've seen before include "known facts" , "Verified fact" , "Beauty is (said Keats)" , "Veracity, faithfulness" , "Candour" .)
