Separate record coming with speed — one minute saved (12)
I believe the answer is:
discriminate
'separate' is the definition.
(I know that separate can be written as discriminate)
'record coming with speed one minute saved' is the wordplay.
'record coming with' becomes 'disc' (I can't explain this - if you can you should believe this answer much more).
'speed' becomes 'rate' (the speed at which something happens).
'one' becomes 'I' (Roman numeral).
'minute' becomes 'min' (abbreviation).
'saved' indicates putting letters inside (save can mean to keep hold of).
'i'+'min'='imin'
'rate' going around 'imin' is 'riminate'.
'disc'+'riminate'='DISCRIMINATE'
Can you help me to learn more?
(Other definitions for discriminate that I've seen before include "Tell apart" , "Show taste" , "Understand the difference (between)" , "Perceive a distinction" , "Perceive the difference - show prejudice" .)
