Issue for year, full of info (7)
I believe the answer is:
progeny
'issue' is the definition.
(thesaurus)
'for year full of info' is the wordplay.
'for' becomes 'pro' (I've seen this before).
'year' becomes 'y'.
'full of' means one lot of letters goes inside another.
'info' becomes 'gen' (gen is a kind of info).
'pro'+'y'='proy'
'proy' going around 'gen' is 'PROGENY'.
(Other definitions for progeny that I've seen before include "seed?" , "Children" , "Issue, offspring" .)
