I mean the “official” or “traditional” alphabet, such as the one taught in schools to children. Is the ordering the same as English? Does it include C, which I notice never seems to show up in native-German words? Does it include ü, ö, ä, and ß? If so, where? Does that mean Germans think of the alphabet as having 30 letters? Or is it less than that with some of them considered variants?
It may seem like a silly question, but my wife was asking and I honestly don’t know because I don’t think I was ever taught these things in German class in college. I never thought about it at the time.
To clarify, the question is: How do native Germans¹ think about their alphabet? For example, Swedes drop w from their alphabet and tack å, ä, and ö onto the end. Spanish speakers consider ñ (and, depending on who you ask, ch and ll) to be a separate letter, but unlike the Swedes they have inserted these into the alphabet in dictionary order. They do not consider accented characters like é to be separate letters. Speaking from that context, how then do Germans think about their alphabet?
I learned in school that the alphabet has 26 letters, A to Z, that was in the 1970s and 80s in Germany. Somehow the umlauts and the eszet were never mentioned when the alphabet was enumerated, I suppose because they are not considered proper letters in German.
As for the letter “c”, we have plenty of them, but in german words they only occur in the combinations “sch”, “ch” and “ck”. These is no special handling for such combinations in german.
As for the ordering, in dictionaries and encyclopedias the umlauts are sorted like the base letter, e.g. “ä” is sorted like “a”. Only if there is a tie then “ä” is sorted after “a”. For example, “Sage” < "Säge" < "sagen" < "sägen".
In phone books umlauts are sorted like base letter + "e", e.g. "ä" is sorted as "ae", etc. This is because phone book contain proper names, which may be written either with umlaut or with base letter + "e", and the correct spelling is not always known. With this sort order such names are still easy to find.
Since you mentioned it, in the Swedish sort order "w" was considered a variant of "v" until 2006, and "ü" is still considered a variant of "y". Both letters were abolished from Swedish words in a relatively recent reform, but continue to exist in proper names.
