Office worker English consider mild in character (9)
I believe the answer is:
temperate
'office worker english consider mild in character' is the definition.
I can't judge whether this defines the answer.
'office worker english consider' is the wordplay.
'office worker' becomes 'temp' (temporary worker in an office).
'english' becomes 'E' (abbreviation).
'consider' becomes 'rate' (I've seen this before).
'temp'+'e'+'rate'='TEMPERATE'
Can you help me to learn more?
(Other definitions for temperate that I've seen before include "With mild climate" , "sober" , "Showing moderation" , "Moderate, mild" , "It is reasonable" .)
