Have you noticed that every language seems to deamonize a particular letter of the alphabet? Users of the language either refuse to pronounce it, or they pronounce it as a different sound, or they banish it altogether.
Polish
Polish has excommunicated the V. This is really strange, because all its linguistic neighbors use the V all the time. All words get rewritten with Ws instead.
Norwegian
Norwegian vowels are heavy, industrial strength. Somehow this has made the O into a Polish U or an English OO. To compensate for this lacking, the Å was invented as a makeshift O.
English
English has caught onto the fact that V and W are really the same sound, and have co-opted the W for a completely different sound. Polish has a ready made letter for this sound: the Ł.
English also disfavors the J, and uses the Y as a J when need be.
Needless to say, the R was mutated into a sound that defies definition. This is lost on many English natives who plainly assume that the crazy English R is the standard for all languages.
French
French refuses to pronounce the H, yet it keeps using it in written form.
French also uses the J as a Polish Ż.
The R, of course, is the most eccentric of them. It was made into a gargling sound that stings the throat.
Dutch
Dutch will pronounce the G only as an H. And the H.. er.. also as an H. It may be that the G and the H are slightly different in speech, but if so it still eludes me how.
Spanish
Spanish doesn't like the J. In its place it improvised the LL (but also the Y is used for this). The J is used as an H, in place of the real H, which refuses to be pronounced. Sounds pretty obsessive, doesn't it?
And the V becomes a B, depending on who you ask.
Italian
Like all its latin friends, Italian pretends the H doesn't exist, but still keeps writing it.
