sätt has the same form in the indefinite singular and plural, like other regular ett words ending in a consonant, so the word sätt in isolation can mean 'way' or 'ways', but here we know it's the singular because it says ett and annat. You could say for instance på några andra sätt 'in some other ways' if you wanted an expression with the plural.
About word order, I wrote a long post here, have you seen it? https://www.duolingo.com/comment/8970470 There are various other helpful threads that you can find via the sticky post under Swedish discussions.
The main answer is already 'in one way or another'. The main answer is the one you can see on top of this page. When your input isn't an accepted answer, the machine tries to match it to the closest answer on file. Also, wherever we write 'one', the machine may show you '1' instead. Any accepted answer can be shown to you. And 'In one or another way' has to be an accepted answer because it's actually an acceptable translation. So because of all this, the answer 'In 1 or another way' may be displayed to you if the machine doesn't accept your input.
This is how the system works for all courses on Duo.
Hi, Arnauti, 1. I would like to verify that "the main answer... you can see at the top of the page." Unfortunately, I have no idea what lesson this is in. Can you remind me?
Question: Why does the machine show "1" instead of numbers? Can someone program the software to show words for numbers one to ten?
You wrote "Any accepted answer can be shown to you." Can you explain how these answers can be shown to me? Maybe you meant possibility (might be shown to you) rather than ability (can be shown to you)? (No intention to criticize your English. I'm just trying to clarify.)
You wrote "And 'In one or another way' has to be an accepted answer because it's actually an acceptable translation." Does this mean the software is checking each word and its translation, meaning that if you come up with a word-for-word translation, e.g. the human race --> det mänskliga loppet," the software will consider this correct?
You wrote "the answer 'In 1 or another way' may be displayed to you if the machine doesn't accept your input." Yet you also wrote "The main answer is already 'in one way or another'." Would you agree that if one enters the wrong answer, the MAIN answer should be displayed and not a random acceptable translation? If so, can this be fixed?
