Waiver can only be used as a noun. It refers to the act of giving up a
right or privilege, including in professional sports the rights to
having a specific player on the team. For instance, opening day for
Major League Baseball was yesterday and there were many players put on
waivers during the preceding month as teams figured out their rosters,
though that process continues the entire year.
Waver, on the other hand, is mostly used as a verb that means to be
unsteady either in opinion, allegiance, physical direction, or even
the volume of sound. A person who is faced with three great selections
of dessert on a menu may waver between which option to choose. Waver
can also be used as a noun to refer to the act of wavering (as
described above) and/or a person who waves (I'm assuming they're
waving hello or goodbye, but maybe they just like to wave in any
situation).
I've included wafer in this list only because it's not uncommon for
people to mishear (or mispronounce) the "v" sound as an "f" sound.
Wafer is most commonly used as a noun to refer to a thin disk, either
of food (like bread or candy) or as a seal or adhesive that has that
thin circular shape. As a verb, wafer refers to the process of sealing
or closing something with a wafer and/or the process of dividing
something (like a silicon rod or ice core) into wafers.
