Says it isn’t on, anyhow, to me (8)
I believe the answer is:
mentions
'says' is the definition.
(mentioning is a kind of saying)
'isn't on anyhow to me' is the wordplay.
'anyhow' indicates an anagram.
'to' says to put letters next to each other (I've seen this in other clues).
'isnt'+'on'='isnton'
'isnton' is an anagram of 'ntions'.
'ntions' put after 'me' is 'MENTIONS'.
'it' is the link.
I am not very happy about this link. It may be part of another bit of the clue.
Can you help me to learn more?
(Other definitions for mentions that I've seen before include "Speaks or writes about briefly or in passing" , "Refers to briefly" , "Alludes to" , "Makes reference to sonnet I'm changing" , "Points out" .)
