Settled, sedate (5)
I believe the answer is:
staid
This clue is a double definition.
'settled' is the first definition.
(I've seen this in another clue)
'sedate' is the second definition.
(I know that sedate can be written as staid)
(Other definitions for staid that I've seen before include "Unadventurous, dull" , "Serious or sober in character" , "Dully unadventurous" , "Proper; sedate" , "Conventional (character)" .)
