Now guess how it feels to type German with predictive text. Most of our words can have more than a dozen different word endings depending on time and how the word is used. And that’s not taking into account that we use compound words, which word prediction pretty much cannot predict and often doesn’t even know. So spell check will mark a legal compound word as misspelled, because it doesn’t understand the concept of compound words and doesn’t know this specific word combination.

To show what I mean, the term “Danube steam boat captain’s hat” becomes “DonauDampfSchiffKapitänsMütze” (I added capital letters which shouldn’t be there to show where the next word in the compound word begins).

While this is an extreme example, it’s pretty common for compound words to consist of 4-5 words.
