Incidentally, I remember being surprised at how well the words worked out. Hēafod is the Old English root for the Middle English and Modern English word, “head.”
vect, or some variation there-of, was also an alternate spelling of a word such as “death” or “die,” but I can’t seem to find the reference. I think it may have come from a Dutch term, because several of there words for “death” and “dead” start with a ve, such as “verouderd.” I’m still looking for the reference.
It has been a while – more than a year, actually – and so I cannot remember exactly, but I believe I took vect, from the Latin word “vacuus,” a term for empty, devoid of or free from. The word sounded like Vecna.
So the term, Vecthēafod is a rather bad contraction for “no head.”
Edit: However, the name vecna comes from a Serbian term for “eternal.” (So when Choo-Choo is shouting “I am eternal” in the July 15/16 – 2003 comic, he’s shouting “I am Vecna” in Serbian.) So Vecthēafod could also be rather bad contraction for “eternal head.”
