Used to be holding husband in which position? (5)
I believe the answer is:
where
'in which position?' is the definition.
(I've seen this before)
'used to be holding husband' is the wordplay.
'used to be' becomes 'were' (I've seen this before).
'holding' means one lot of letters goes inside another.
'husband' becomes 'h'.
'were' placed around 'h' is 'WHERE'.
(Other definitions for where that I've seen before include "At which point" , "A question of place?" , "a question of location" , "In which position?" , "enquiry" .)
