Hopeful individual omits tip, oddly (8)
I believe the answer is:
optimist
'hopeful' is the definition.
(thesaurus)
'omits tip oddly' is the wordplay.
'oddly' indicates anagramming the letters.
'omits'+'tip'='omitstip'
'omitstip' is an anagram of 'OPTIMIST'.
'individual' is the link.
I am not very happy about this link. It may belong to another bit of the clue.
Can you help me to learn more?
(Other definitions for optimist that I've seen before include "I expect more?" , "One wearing rose-tinted spectacles" , "One always sees the glass as half-full" , "cheerful type" , "I hope for the best" .)
