a grave God-fearing man.
a quiet sedate nature.
A sobering thought.
a solemn promise.
After thinking about the potential consequences of his plan, he sobered up.
as sober as a judge.
children in somber brown clothes.
drab faded curtains.
Keep him in bed until he sobers up.
sober Puritan grey.
the judge was solemn as he pronounced sentence.
