Get a rash possibly going to a very hot dry region (6)
I believe the answer is:
sahara
'hot dry region' is the definition.
'Sahara' can be an answer for 'region' (Sahara is an example). I'm not sure about the 'hot dry' bit.
'get a rash possibly going to a' is the wordplay.
'get' means one lot of letters go next to another.
'possibly' indicates anagramming the letters.
'going to' is a charade indicator (letters next to each other).
'a' next to 'rash' is 'arash'.
'arash' anagrammed gives 'sahar'.
'sahar'+'a'='SAHARA'
'very' acts as a link.
Can you help me to learn more?
(Other definitions for sahara that I've seen before include "World's largest desert" , "Great desert in N Africa" , "Hottest desert" , "About 3,500,000 square miles of Africa" , "World's largest sandy area" .)
