As eaten up in the stratosphere? (5)
I believe the answer is:
tarts
'as eaten up' is the definition.
I can't tell whether this definition defines the answer.
'the stratosphere?' is the wordplay.
'TARTS' is hidden back-to-front in amongst the letters.
However, I'm uncertain how this is indicated.
'in' acts as a link.
Can you help me to learn more?
(Other definitions for tarts that I've seen before include "Small open pies" , "cakes" , "Broads" , "women (that may be offensive)" , "Desserts" .)
