One gets rid of letters from Queen after ages (6)
I believe the answer is:
eraser
'one gets rid of letters' is the definition.
I can't judge whether this definition defines the answer.
'queen after ages' is the wordplay.
'queen' becomes 'er' (abbreviation for Elizabeth Regina).
'after' means one lot of letters go next to another.
'ages' becomes 'eras' (I've seen this before).
'er' put after 'eras' is 'ERASER'.
'from' acts as a link.
Can you help me to learn more?
(Other definitions for eraser that I've seen before include "Obliterator" , "destroyer" , "What a poor artist needs" , "A schoolboy's rubber" , "Rubber, thing that wipes out" .)
