Animated miner quietly parking in Welsh town for festival (5)
I believe the answer is:
happy
'welsh town for festival' is the definition.
I can't tell whether this defines the answer.
'animated miner quietly parking in' is the wordplay.
'animated miner' becomes 'hay' (I can't explain this - if you can you should believe this answer much more).
'quietly' becomes 'p' (p for piano and quiet).
'parking' becomes 'p' (abbreviation on road signs).
'in' indicates putting letters inside.
'p'+'p'='pp'
'hay' enclosing 'pp' is 'HAPPY'.
Can you help me to learn more?
(Other definitions for happy that I've seen before include "Fortunate; content" , "Cheerful - dwarf" , "Blissful" , "Contented" , "Carefree" .)
