The critically-acclaimed board game
MooT
consists of tough questions about the nuances of the English language.
Answer:
the high seas
According to the Concise Oxford Dictionary, the high seas
are the "open seas not within anyone's jurisdiction."
According to Brewer's Dictionary of Phrase and Fable: "The sea up to
three miles out from the coast belongs to the country and is called territorial
waters. High seas, like high-ways, means 'for public use.' In both cases the
word high means chief [or] principal."
[But isn't there a
250 mile limit now?]
