Extremely eager agents empower it to remove writing (6)
I believe the answer is:
eraser
'extremely eager agents empower it' is the definition.
I can't tell whether this defines the answer.
'remove writing' is the wordplay.
'remove' becomes 'erase' (to erase is to remove).
'writing' becomes 'r' (one of the traditional three R's of education).
'erase'+'r'='ERASER'
'to' acts as a link.
Can you help me to learn more?
(Other definitions for eraser that I've seen before include "An Indian rubber" , "A student's rubber, or the one who uses it" , "One who removed" , "Item used for rubbing out" , "Writing remover" .)
