A seer is trained to wipe the tape (5)
I believe the answer is:
erase
'wipe the tape' is the definition.
'erase' can be an answer for 'wipe' (I've seen this in another clue). I'm unsure of the 'the tape' bit.
'a seer is trained' is the wordplay.
'is trained' indicates anagramming the letters (to train can mean to grow something into a shape).
'a'+'seer'='aseer'
'aseer' with letters rearranged gives 'ERASE'.
'to' is the link.
Can you help me to learn more?
(Other definitions for erase that I've seen before include "Do away with" , "Rub out, cancel" , "Remove recorded material" , "Destroy recording on audio or video tape" , "Remove permanently" .)
