So how does Finnish compare up? Do you not have silent letters?
In Dutch we have some useless things like combined letters: "c" and "h" are both used (like in "cake" or "hotel") but when combined to "ch" they sound like a "g". There are even duplicate ones: "au" and "ou" are both the same sound, and "ij" and "ei" too. You can't mix them though, "ijs" is ice and "eis" is a demand even though they sound 100% the same. I'm not sure about silent letters though, the "h" is audible even if only slightly.
