Games packed in Orcadian island with any luck (9)
I believe the answer is:
hopefully
'island with any luck' is the definition.
I can't tell whether this defines the answer.
'games packed in orcadian' is the wordplay.
'games' becomes 'PE' (abbreviation for Physical Education).
'packed' becomes 'full' (synonyms).
'in' means one lot of letters goes inside another.
'orcadian' becomes 'hoy' (I can't explain this - if you can you should give a lot more credence to this answer).
'pe'+'full'='pefull'
'pefull' put into 'hoy' is 'HOPEFULLY'.
Can you help me to learn more?
(Other definitions for hopefully that I've seen before include "If all goes well" , "With the desire for fulfilment" , "Optimistically" , "With anticipation" , "It's better to travel this way than to arrive, perhaps" .)
