Defer to appropriate article on wet weather study (4,1,9)

'defer' is the definition.
I don't know anything about this answer so I cannot tell whether it can be defined by this definition.

'appropriate article on wet weather study' is the wordplay.
'appropriate' becomes 'take' (appropriate can mean to steal).
'article' becomes 'a' (the indefinite article in English).
'on' means one lot of letters go next to another.
'wet weather' becomes 'rain' (rain is wet weather).
'study' becomes 'check' (checking is a kind of studying).
'take'+'a'+'rain'+'check'='TAKE A RAINCHECK'

'to' is the link.

Can you help me to learn more?
