Scheme to set off for worlds in space (7)
I believe the answer is:
planets
'worlds in space' is the definition.
The answer and definition can be both natural objects as well as being plural nouns.
Maybe there's a link between them I don't understand?
'scheme to set off' is the wordplay.
'scheme' becomes 'plan' (synonyms).
'to' says to put letters next to each other.
'off' indicates anagramming the letters.
'set' is an anagram of 'ets'.
'plan'+'ets'='PLANETS'
'for' acts as a link.
Can you help me to learn more?
(Other definitions for planets that I've seen before include "Heavenly bodies" , "Celestial bodies" , "Ten laps (anag.)" , "Big bodies" .)
