PIE *ueid, *uid

PIE *ueid, uid

This PIE root meant -so far I know- " to see, catch sight of; perceive
". In some languages it developed a sense of " to know" like in German
languages.

I know followings cognates in the actual IE languages:

German: wissen

Gothic: witan

Latin : videre

Greek : idein, eidenai, idea

Russian: videt ( I guess all slavic languages have the root "vid-" for "
to see")

Prygian: wit= to know, witeto = he looked ( isnt it "e-witeto"?)

I have a question here. Is the Prygian pronunciation supposed to have
been with "v" like in Germanic and Latin or with "u" like in English
"wait"?

From all languages it seems just Greek language changed the "ue-, ui-"
in an "ei, i" so I will like to inform myself if there are other
cognates in other IE languages where the PIE "ue-" became something
else, but not "v" like in Slavic , Latin and Germanic.
