Remove bearings after a time (5)
I believe the answer is:
erase
'remove' is the definition.
(to erase is to remove)
'bearings after a time' is the wordplay.
'bearings' becomes 'se' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'after' says to put letters next to each other.
'a time' becomes 'era' (an era is a period of time).
'se' after 'era' is 'ERASE'.
Can you help me to learn more?
(Other definitions for erase that I've seen before include "score" , "Delete" , "Eliminate" , "Remove, wipe out" , "Remove evidence of" .)
