Take no notice of Glen, etc. (7)
I believe the answer is:
neglect
'take no notice' is the definition.
The answer and definition can be both acts as well as being singular nouns.
Perhaps they are linked in a way I don't understand?
'of glen etc' is the wordplay.
'of' is an anagram indicator (the answer comes from or 'of' the letters).
'glen'+'etc'='glenetc'
'glenetc' is an anagram of 'NEGLECT'.
Can you help me to learn more?
(Other definitions for neglect that I've seen before include "Fail to look after (something)" , "Give little attention to" , "Disregard or fail to care for" , "Failure to do something" , "Leave unattended, disregard" .)
