|Notes:||Though with different stem elements, the root is still
considered to be the same for all IE languages. Its two varieties, with *-kw-
and with *-p-, originally had different tints of meaning; it seems that the
latter meant 'she-wolf' in Proto-Indo-European.
As every other common Indo-European term denoting wild animals, this one confirms that the Indo-European homeland was situated in a region where wolfs could be found.
