Travelling to stars: reduced pressure in this place? (12)
I believe the answer is:
stratosphere
'travelling' is the definition.
Although both the answer and definition are singular nouns, I can't see how one could define the other.
'to stars reduced pressure in this place?' is the wordplay.
'reduced' indicates anagramming the letters.
'pressure' becomes 'p' (abbreviation).
'in this place?' becomes 'here' ('here' can be a synonym of 'in this place').
'to'+'stars'='tostars'
'tostars' is an anagram of 'stratos'.
'stratos'+'p'+'here'='STRATOSPHERE'
Can you help me to learn more?
(Other definitions for stratosphere that I've seen before include "Region about ten to fifty km above the earth" , "Area containing ozone layer" , "Layer above the earth where temperature generally increases with height" , "Atmospheric layer" , "Zone high above earth" .)
