Yes, you use it to talk about location, it just means you say where something is!.. also:
Use om to mean "about", but never with approximations, with that I mean, you cannot use om to refer to the number of people in one place, for example. .(There are about/around three book in my backpack- don't use om), so:
• A book about Einstein: en bok om Einstein. • We talk about you: vi pratar om du
When talking about time, you use om to mean "in"/ "within":
• I'll be there in four hours: Jag kommer att vara där om fyra timmar, and yes!, you can also use i here! •In two decades: om två årtionden.
Ufff, one more! om also means "around", referring to a place, and never approximations of quantities, as explained above, Here runt and kringare also possible:
• Marie has flowers around her house: Marie har blommor om/runt/kring hennes hus.
•I put a fence around the yard: Jag satte ett staket runt gården
It means "a" when referring to a daily or yearly frequency, here the "formula" is om + noun(en- et), so, let's see: •I go to school twice a day: jag går till skolan två gånger om dagen.
•Jag reser till England fem gånger om året. You can say "per år" when you don't talk about a daily or yearly frequency you say like that: "i + noun(en-et)" or "per + noun":
•I work three times a week: Jag arbetar tre gånger i veckan/ per vecka
• My father likes to walk through the park four times a week: Min pappa gillar att gå igenom parken fyra gånger i veckan/ per vecka
It means "of" when you mean possession, but it is not much used!
Thanks for all these (and the effort)! I'd give you a lingot but I'm on mobile >_>
Generally speaking, we use om for location and av for possession. There are more differences, but that's the reason we use om in this case.
(For anyone who knows a bit about situated language processing, om is used for grounding relative entity placements.)
Kan någon förklara när man använder "norr", "norra" i "nord"? also, what are the equivilents for the other directions?
