Plain bothies in disrepair providing no shelter (12)
I believe the answer is:
inhospitable
'providing no shelter' is the definition.
I can't judge whether this defines the answer.
'plain bothies in disrepair' is the wordplay.
'in disrepair' indicates anagramming the letters.
'plain'+'bothies'='plainbothies'
'plainbothies' anagrammed gives 'INHOSPITABLE'.
Can you help me to learn more?
(Other definitions for inhospitable that I've seen before include "Unfriendly" , "Difficult to live in" , "Hostile" , "Harsh, inimical to life" .)
