I would say so, yes, although they both translate to 'happy', and explaining the difference between them isn't the easiest. This is how I would explain it: 'Lycklig' is a longer lasting sentiment, and also goes deeper, as in being happy in life. I would translate happy to lycklig in these sentences:
- Ever since I met you, I've felt so happy.
- You make me happy. (more intimate with 'lycklig')
I would translate happy to 'glad' in these sentences:
- I'm happy you came.
- I'm happy to be here.
- You make me happy. (more friendly with 'glad')
I'm sorry if that's not super clear, the words can be easily exchanged, but MY opinion is that they do differ somewhat. :)
No.To look and seem to be something are not the same. 'Verkar' translates to 'seem'. 'Ser ut' translates to 'look'. I'd say that the main difference would be based on apperance - for example you can make a judgement on somebodys mood when talking to them on the phone. Then they seem happy. But if you meet up with somebody and they are smiling, you could say either or. But they still don't mean the same thing.
