Vivid rag variety caught in a medicine-bottle (9)
I believe the answer is:
graphical
'vivid' is the definition.
Both the definition and answer are adjectives. Perhaps there's an association between them I don't understand?
'rag variety caught in a medicine-bottle' is the wordplay.
'variety' indicates anagramming the letters.
'caught' becomes 'c' (cricket abbreviation).
'in' is an insertion indicator.
'a medicine bottle' becomes 'phial' (I've seen this before).
'c' inserted into 'phial' is 'phical'.
'rag' is an anagram of 'gra'.
'gra'+'phical'='GRAPHICAL'
Can you help me to learn more?
(Other definitions for graphical that I've seen before include "relating to plots?" , "Relating to visual art" .)
