Sober, Paddy had a meal (9)
I believe the answer is:
temperate
'sober' is the definition.
(thesaurus)
'paddy had a meal' is the wordplay.
'paddy' becomes 'temper' (I've seen this in other clues).
'had a meal' becomes 'ate'.
'temper'+'ate'='TEMPERATE'
(Other definitions for temperate that I've seen before include "comfortably warm?" , "pleasant" , "Restrained" , "Moderate, mild" , "With mild climate" .)
