Moderate, mild (9)
I believe the answer is:
temperate
I believe this is a double definition.
'moderate' is the first definition.
(I know that moderate can be written as temperate)
'mild' is the second definition.
(similar in meaning)
(Other definitions for temperate that I've seen before include "Moderate, mild" , "even" , "Restrained" , "comfortably warm?" , "Calm" .)
