Identity of Half-Blood Prince

[Fiona]

No: HPFGUIDX 121935



I recently bought myself a Latin-English dictionary to help me with 
my writing and I came across an entry for PRINCE.

prince - noun  -  regulus, regis, filius

The entry got me to thinking back over the role of the diminutive 
charms professor and to wondering if JKR is trying to wrong-foot us 
into thinking the prince has to be a major character.  Perhaps 
Flitwick is half-human half-goblin?  It opens some interesting 
possibilities.
