*u̯eig-

This is one of the roots that was about:

bending, winding (also: changing)

It doesn’t have too many offspring in English, but certainly some surprisingly ones.
Here’s a little (incomplete) overview:

• wicker (“winding tree”)
• vice- (“taking the place of”)
• weak (“easy to bend”)
• week (“the change of times”)
• vice versa (“change to the counter as well”)
