We feel you over here in Sweden. Särskrivning (roughly “word splitting”) is a “problem” far greater than the apostrophes for us. Americentric Swedish Android keyboards are terrible offenders that happily splits words in two.
This is how language evolves nowadays. :/
If they train the predictive text function on swedish text, I don't know why it would do English-y things, and if they didn't train it on Swedish how does it work at all?
It's very surprising, and interesting, to me that this category of problem, in this particular context, is even possible
Personally I think our "language culture" is overrated and I wouldn't care if Dutch just disappeared completely in favour of English.
In German it also knows Computer and Tastatur, but I can’t use autocomplete to type Computertastatur.
Actually I just learned I can. Apparently this word is in the dictionary. But there are just so many compound nouns, it’s impossible for them all to be in the dictionary.
To make it work in such a language it has to understand about constructing compound nouns.
Also In Swedish splitting the words is many cases not incorrect, but just changes the meaning.
For example is Swedish an "English teacher" (Engelsk lärare) would be a teacher that is from England, while an "Englishteacher" is a teacher the teaches the subject English.
So "He is an English teacher" and "He is an Englishteacher" would both be valid sentences in Swedish, but the predictive text model seems to assume you wanted the first one.
