Weird legal terms
Interesting but just as often a cause of disbarment in actual practice as anything else
It's not really clear where the term "curtilage" originates.

There's something vaguely shameful about the term, like dog do on the front porch. It's not really clear that there is any precise legal definition, but it's rather a situation where people need to curb their dogs and stay off the property and you might need to put up a fence for privacy.
"Laches" is another one. It's the same word in modern French spelled "lâchesse" meaning "looseness" in English. Is there a latch on the front door of your home, or do you need to lock your door as well? Merely latching the door is apparently not enough to keep inquisitive busybodies and peeping toms out, in case you chance being caught bathing or in a atate of undress in your own home.

Or "estoppel by laches", essentially, "You let it go, you can't have it back!"
It's very subtly indecent to call a woman "loose" on her own property like that in court.
