Why is Latin lupus 'wolf' lupus rather than +vulpus? Is there a rule
l.kW > lukW parallel to the development of Greek lukos from PIE
*wl.kWos? I presume similar arguments apply whether you accept PIE
*wl.kWos or elaborate PIE to have wl.pWos to neatly account for
Germanic *wulfaz. (There appears a 'lesser wild dog' root with
consonants wlp - see
http://groups.yahoo.com/group/cybalist/message/14885 for a list.)
