Thoughts from Sadie (5)
I believe the answer is:
ideas
'thoughts from sadie' is the definition.
(I've seen this before)
'from sadie' is the wordplay.
'from' is an anagram indicator (from the letters).
'sadie' anagrammed gives 'IDEAS'.
(Other definitions for ideas that I've seen before include "Thoughts, creative perhaps" , "plans" , "Notions, concepts" , "Thoughts, maybe creative" , "Thoughts, concepts" .)
