Production of tangerine in orbit without oxygen (10)
I believe the answer is:
generation
'orbit without oxygen' is the definition.
I can't judge whether this definition defines the answer.
'production of tangerine' is the wordplay.
'production' indicates an anagram.
'of' becomes 'o''.
'o'+'tangerine'='otangerine'
'otangerine' with letters rearranged gives 'GENERATION'.
'in' is the link.
Can you help me to learn more?
(Other definitions for generation that I've seen before include "Everyone of same age" , "what was lost in WW1" , "Group born around same time" , "group of similar age" , "peer group" .)
