Husband with dashing looks initially wandering in mountainous area (9)
I believe the answer is:
highlands
'mountainous area' is the definition.
(I've seen this before)
'husband with dashing looks initially wandering' is the wordplay.
'husband' becomes 'h' (abbreviation).
'with' says to put letters next to each other.
'initially' indicates taking the first letters.
'wandering' is an anagram indicator.
The initial letter of 'looks' is 'l'.
'dashing'+'l'='dashingl'
'dashingl' is an anagram of 'ighlands'.
'h'+'ighlands'='HIGHLANDS'
'in' acts as a link.
(Other definitions for highlands that I've seen before include "Scottish mountains" , "Mountainous area" , "region of Scotland" , "upper part of Scotland" , "mountainous region" .)
