Man who confuses passion with home (4,7)
I believe the answer is:
homo sapiens
'man' is the definition.
(Homo sapiens is an example)
'confuses passion with home' is the wordplay.
'confuses' indicates an anagram.
'with' is a charade indicator (letters next to each other).
'passion' after 'home' is 'homepassion'.
'homepassion' is an anagram of 'HOMO SAPIENS'.
'who' is the link.
(Other definitions for homo sapiens that I've seen before include "The one existing species of Man" , "Modern humans" , "Relative of 1 across" , "Human species" .)
