In the Navy, if you’re told to “belay that”, it means to ignore whatever it was you were last ordered to do.
Ex. If the pirate captain said “aha swab the deck, belay that, load that cannon” you should load the cannon.
My dictionary thinks that “Avast!” (from the 17th century), might come from Dutch “hou’ fast” (hold fast) so maybe that’s one for Coldfire. Sadly, it doesn’t know anything at all about “Arrg”. That has ruined my whole day.
“Hold fast”… does that mean the same as “hold on tight”, or “grip tight”? Cause that’s what the Dutch phrase “hou(d) vast” means literaly (the “d” ending “houd” indicates the more formal version - spoken language is usually “hou”).
Lucky for you, I have my notes from when the U.S. Brig Niagara came to New York City for OpSail 2000 this past summer. (The ship is a re-creation of one that served on Lake Erie in the war of 1812.)
The mate told us:
This is used b/c:
As the capt. shouts an order forward from his post at the “flying bridge,” his officers on deck repeat the order in succession. If the capt. hears that one of them has misunderstood and is repeating the wrong thing, he shouts out “AVAST!”, everyone stops, and then he calls the correct order again.
A SWAG on the “Aarr…” business; as Robt Louis Stevenson knew full well, the southwest coast of England was well-known for its smugglers, wreckers and general swashbucklery. The natives of Cornwall (and parts of Devon) do have a rather interesting dialect, in particular saying “Arrr” to mean “Aye” or “Yes.” This is often burlesqued by British comics (think of the “killer rabbit” scene in Monty Python and the Holy Grail, where someone says, “There’s a St Aaarrrgh in Cornwall!”).
To address the OP: perhaps, since Stevenson’s extremely widely-read “Treasure Island” gave Cornwall and Devon as the locus of many of the pirate characters, their dialect has become the “standard” caricature pirate-talk?
Wandering slightly off-topic…I recall a PBS series 10-20 years ago about the English language (“History of English”,or something like that, hosted by Robert McNeil). One episode posited that the Cornwall dialect was more widespread in the 16th century, and was close to standard pronunciation. Which raises the wonderful image of the Elizabethan court all talking like pirates.
Alrighty then here’s a good tester for you, lets see if anyone gets it.
When I shout out the order “Two-six, heave!” What do I normally mean by that and from where does it come ?
By way of a clue, yes I have actually done it in its original meaning when I was dragged into some film work for the Royal Navy on HMS Victory, couldn’t have been anywhere else I suppose.
