Celebrity ignoring a noted scientist (6)
I believe the answer is:
lister
'celebrity ignoring a noted scientist' is the definition.
I can't judge whether this defines the answer.
'celebrity ignoring a noted scientist' is the wordplay.
'celebrity' becomes 'a list' (I've seen this before).
'ignoring' suggests deleting specific letters.
'noted scientist' becomes 'er' (I can't explain this - if you can you should give a lot more credence to this answer).
'alist' with 'a' removed is 'list'.
'list'+'er'='LISTER'
Can you help me to learn more?
(Other definitions for lister that I've seen before include "Plough" , "surgeon?" , "Pioneer of antiseptic surgery" , "Man introducing antiseptics" , "One with leanings" .)
