It describes husband and wife (6)
I believe the answer is:
spouse
'wife' is the definition.
(a wife is a female spouse)
I don't understand the rest of the clue.
Can you help me to learn more?
(Other definitions for spouse that I've seen before include "Very hot and dry" , "Other half" , "Partner in marriage" , "Elizabethan dance" , "Possibly wife" .)
