Quiet Hampshire arts master disturbed by a ghostly vision (9)
![Ross](/clue/static/ross-mug.min.png)
I believe the answer is:
phantasma
'ghostly vision' is the definition.
'phantasma' can be an answer for 'vision' (thesaurus). I am not sure about the 'ghostly' bit.
'quiet hampshire arts master disturbed by a' is the wordplay.
'quiet' becomes 'p' (music symbol for 'piano', ie soft or quiet).
'hampshire' becomes 'Hants' (postal abbreviation).
'arts master' becomes 'ma' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'disturbed by' indicates putting letters inside (inserted letters disrupt or disturb the word).
'hants'+'ma'='hantsma'
'hantsma' enclosing 'a' is 'hantasma'.
'p'+'hantasma'='PHANTASMA'
Can you help me to learn more?
