State learning in abundance (6)
I believe the answer is:
galore
'in abundance' is the definition.
(thesaurus)
'state learning' is the wordplay.
'state' becomes 'ga'.
'learning' becomes 'lore' (I've seen this before).
'ga'+'lore'='GALORE'
(Other definitions for galore that I've seen before include "'Whisky ------!', classic Ealing comedy of 1949" , "Pussy ---, Bond girl" , "to spare" , "Existing in great numbers" , "abundantly" .)
