A lot of childhood disease linked to seaside location? I'd keep an eye on the games played (8)
I believe the answer is:
croupier
'seaside location? i'd keep an eye on the games played' is the definition.
I can't tell whether this defines the answer.
'a lot of childhood disease linked to' is the wordplay.
'a lot of childhood' becomes 'ier' (I can't justify this - if you can you should believe this answer much more).
'disease' becomes 'croup' (croup is a kind of disease).
'linked to' means one lot of letters go next to another.
'ier' after 'croup' is 'CROUPIER'.
Can you help me to learn more?
(Other definitions for croupier that I've seen before include "official at the gaming table" , "Gaming table worker" , "Manager of a gambling table" , "Person in charge of gambling-table" , "Casino dealer" .)
