Summarizing everything: we have learnt att vilja (to want) - vill (want), att kunna (to be able to) - kan (can), then ska (shall/will) and now we also know the words göra and något.
We have learned that to make verbs from to do into Ido or hedoes you simply remove att and add an r. That was the first category and it includes over 80% of all words, so that’s a pretty safe bet to do so.
There are, however, a few other ways to do it. Let’s learn one more:
Swedish for to need is att behöva.
Think I need to behave.
The word behöva is one of the verbs that we will call the er-words. They are special because the er-words do not like the ending ar, so they do not simply add the r but also change the letter before to e. Thus their ending becomes er.
