Okay, I had my usual bad luck with this search engine, and nothing sounded appropriate on google, so I’m posting my question here.
After mopping the floor in the kitchen and dining rooms today, I said to no one there (D was at a family gathering), “Okay these rooms are off-limits until they dry”.
And then I wondered “Why is it called that? Shouldn’t it be ‘on-limits’, if you’re limiting traffic across a wet floor?”
So, because you guys are the champs, I’ll ask you. Why is it called that?
The limits don’t apply to the people, they apply to the territory.
Think of your house as an army base. You’re the general, your kids are the new recuits (with boots).
New soldiers are allowed to wander within the limits of the base.
But anything beyond, is “off limits”.
Especially if the kitchen floor is still wet, and the boots are muddy.
The word “off” once meant something more like “away from,” rather than “not on top of,” which is its more typical meaning today. So “off limits” meant something like “away from the limits,” which could be interpreted as being outside the limits:
