Se ut som is ’to appear, to look like smth’ as in ”Den ser stor ut.” (It looks big) whereas titta is just ’to use your eyes, to look, to watch’.
I figured. I was going to make the comparison with se ut som being like the Spanish verb parecer (which I am assuming you are familiar with). Titta, then, must be like ver or mirar, right?
Is på always necessary with tittar? As in, can tittar ever be used on its own? Thanks in advance :)
With an object it is always necessary. But if there's no object, it's not used. Like Tittar du eller inte? 'Are you looking or not?'
på in this case is a preposition so it's not stressed. To make things more complicated, there is also a particle verb tittar på where på is always stressed. This verb has a slightly different meaning. It cannot take an object, but it always has the particle. So with this verb, it would be Tittar du på eller inte? 'Are you watching or not?' – the difference in meaning is very small in this case.
No, åt with directions is only used for more general directions. Like åt höger 'to the right'.
So how would you say: look to the right. Like in a sightseeing for example? Or: Watch out at your right! To warn someone from something that is on his right? Tack!
