Pay no attention to part of education, e.g. lectures (7)
I believe the answer is:
neglect
'pay no attention to' is the definition.
(thesaurus)
'part of education e g lectures' is the wordplay.
'part of' indicates the answer is hidden within the clue.
'NEGLECT' is hidden within 'education e g lectures'.
(Other definitions for neglect that I've seen before include "Lack of proper care" , "Insufficiently attend to" , "Failure to give proper care" , "Heedlessness" , "Disregard or fail to care for" .)
