the building you're standing in, legally speaking, and the reasons you're standing there, logically speaking.
means a physical property with its buildings and land, or the starting assumptions of an argument — one word, two completely unrelated meanings by legal fluke.
from from latin praemissa, things put before — in logic, the statements set before a conclusion. law contracts used to list a property in detail, then say the premises for short in later clauses. eventually the shorthand became the noun, and the word walked off with a whole new job.
