Gravity in orbit? Yes, in a different way (8)
I believe the answer is:
sobriety
'gravity' is the definition.
(synonyms)
'orbit? yes in a different way' is the wordplay.
'orbit? yes' can be anagrammed to 'SOBRIETY'.
Though, I am not clear how the anagram is indicated.
'in' acts as a link.
Can you help me to learn more?
(Other definitions for sobriety that I've seen before include "characteristic of judge, supposedly" , "restraint" , "The avoidance of too much alcohol" , "Rational, non-intoxicated condition" , "Abstemiousness" .)
