Changes are on table for sensible person (7)
I believe the answer is:
realist
'sensible person' is the definition.
'realist' can be an answer for 'person' (realist is a kind of person). I'm not certain of the 'sensible' bit.
'changes are on table' is the wordplay.
'changes' indicates anagramming the letters.
'on' is a charade indicator (letters next to each other).
'table' becomes 'list'.
'are' is an anagram of 'rea'.
'rea'+'list'='REALIST'
'for' acts as a link.
Can you help me to learn more?
(Other definitions for realist that I've seen before include "no dreamer" , "Pragmatic type" , "Sensible and practical person" , "Practical sort" , "One with a pragmatic attitude" .)
