Possibly said to hold the key to inventiveness? (5)
I believe the answer is:
ideas
'to inventiveness?' is the definition.
I can't tell whether this defines the answer.
'possibly said to hold the key' is the wordplay.
'possibly' is an anagram indicator.
'to hold' means one lot of letters goes inside another.
'the key' becomes 'E' (a musical key).
'said' is an anagram of 'idas'.
'idas' placed around 'e' is 'IDEAS'.
Can you help me to learn more?
(Other definitions for ideas that I've seen before include "Brainwaves" , "Thoughts, perceptions" , "Thoughts, maybe creative" , "plans" , "Notions, thoughts" .)
