Learned to ignore first repeat (7)
I believe the answer is:
iterate
'repeat' is the definition.
(synonyms)
'learned to ignore first' is the wordplay.
'learned' becomes 'literate' (synonyms).
'to ignore first' means to remove the first letter (I've seen 'ignoring first' mean this).
'literate' with its first letter removed is 'ITERATE'.
(Other definitions for iterate that I've seen before include "Say again, repeat" , "Utter or perform repeatedly" , "State repeatedly, say again" , "Recapitulate" , "Repeat, state again" .)
