Type of information on America (5)
I believe the answer is:
genus
'type' is the definition.
(I've seen this before)
'information on america' is the wordplay.
'information' becomes 'gen' (gen can informally mean information).
'on' says to put letters next to each other.
'america' becomes 'US' (United States).
'gen'+'us'='GENUS'
'of' acts as a link.
(Other definitions for genus that I've seen before include "Latin class?" , "Category between family and species" , "species grouped together" , "Division of family" , "group of organisms" .)
