I've noticed both ligger and står being used to give location. What's the difference?
It depends on the shape of the object. If a book is lying flat on the table, we’d use ”ligger” (lying) but if it’s upright in a bookshelf we’d use ”står” (standing). For cities and such, it’s always ligger.
So if I wanted to say, "The tower is located on an island," would I say "Tornet står på en ö"?
I could say something like Baren revs, och nu står där ett höghus i stället.
Not that I can think of. However, some letters spelled out phonetically turn into nouns: bee, sea, jay, pee, tea.
The "I" is an alternative term for the metaphysical ego. Musical notes such as C, F, etc. are nouns. Grades such as B, D, etc. are nouns.
Actually, I think most letters if not all are nouns in one form or another, but to which extent some may be abbreviations is open for debate, I guess. :)
