A seer in a flurry to get off the mark (5)
I believe the answer is:
erase
'mark' is the definition.
The answer and definition can be both related to change as well as being verbs in their base form.
Maybe they are linked in a way I don't understand?
'a seer in a flurry to get off' is the wordplay.
'a seer' anagrams to 'ERASE'.
But, I'm not sure how this is indicated.
'the' acts as a link.
Can you help me to learn more?
(Other definitions for erase that I've seen before include "Blank out" , "Scratch" , "Remove permanently" , "Rub out, cancel" , "Remove from memory" .)
