Seated with The Sun perhaps, taking in garden before end of day (9)
I believe the answer is:
sedentary
'seated' is the definition.
(thesaurus)
'sun perhaps taking in garden before end of day' is the wordplay.
'sun perhaps' becomes 'star' (sun is a kind of star).
'taking in' means one lot of letters goes inside another.
'garden' becomes 'eden' (Garden of Eden in the Bible).
'before' means one lot of letters go next to another.
'end of' says to take the final letters.
The final letter of 'day' is 'y'.
'star' going around 'eden' is 'sedentar'.
'sedentar'+'y'='SEDENTARY'
'with the' acts as a link.
(Other definitions for sedentary that I've seen before include "not exercising one's talents?" , "describing many office jobs?" , "Tending to spend much time seated" , "inactive" , "Tending to stay seated" .)
