Ideas Greek character vocalises (7)
I believe the answer is:
musings
'ideas' is the definition.
The definition and answer can be both related to thinking as well as being plural nouns.
Perhaps there's a link between them I don't understand?
'greek character vocalises' is the wordplay.
'greek character' becomes 'mu' (letter from the Greek alphabet).
'vocalises' becomes 'sings' (I've seen this in another clue).
'mu'+'sings'='MUSINGS'
Can you help me to learn more?
(Other definitions for musings that I've seen before include "Thoughts" , "dreams" .)
