By and Large: How Sailors Gave English So Much of Its Vocabulary

For the better part of a thousand years, the sea was where English-speakers did their most demanding, specialised and dangerous work, and specialised work breeds specialised words. A crew had to name every rope, every angle of the wind and every stage of a manoeuvre precisely enough to shout it in a gale. When those sailors came ashore, the vocabulary came with them, and much of it drifted from the technical into the everyday until we forgot it had ever smelled of salt. The trouble is that the sea’s genuine gift to English is generous enough that people keep trying to make it larger, and a good half of “nautical origin” stories turn out to be landlubbers’ inventions.

By and large: the real thing

Start with the phrase that gives this piece its title, because it is a clean example of a metaphor that means nothing until you know the ship. To sail “by” is to sail close to the wind, as near to its source as the rigging will allow; to sail “large” is to run with the wind coming from behind, over the quarter. A vessel that handled well “by and large” behaved itself whether pointed up into the wind or running free — in all conditions, on the whole. Landsmen took the phrase and kept only the “on the whole,” discarding the ship entirely. That is the classic life-cycle of a nautical idiom: a precise instruction becomes a vague generality once the people using it no longer need the precision.

Several everyday expressions have the same clean pedigree. To be “taken aback” is what happens when a sudden shift of wind strikes the front of the sails and presses them flat back against the mast, checking the ship’s way — exactly the sensation of being stopped short by surprise. To “know the ropes” was to understand the bewildering rigging of a sailing ship well enough to be useful. And “three sheets to the wind,” for someone thoroughly drunk, turns on a piece of vocabulary most people get wrong: a “sheet” is not a sail but the rope controlling one. Let three sheets fly loose and the sails flap uncontrolled; the ship lurches and staggers like a drunk.

The bitter end: where honesty starts

Then there is “the bitter end,” which is worth dwelling on because it shows both how good a nautical explanation can be and why even a good one deserves a raised eyebrow. On a ship, the bitts are the stout posts fixed to the deck around which the anchor cable is wound. The turn of cable around them is a “bitter,” and the “bitter end” is the very last of the cable, the part that stays aboard. Pay out the anchor rope until you reach the bitter end and there is quite literally no more rope: you have gone as far as you can go.

This is not a modern guess. Captain John Smith — the same Smith of the Jamestown colony — set it down in his Sea Grammar of 1627:

“A Bitter is but the turne of a Cable about the Bits, and veare it out by little and little. And the Bitters end is that part of the Cable doth stay within boord.”

That is a genuine seventeenth-century mariner explaining the term in a technical manual, which is about as good as etymological evidence gets. And yet the careful reference sites still decline to close the case, because “bitter” also has its ordinary meaning — an end that is grim, painful, the taste of defeat — and it is entirely possible the everyday phrase drew on that sense and only later got tangled with the sailors’ bitts. The best-informed verdict is a shrug: the nautical account is credible and early, but not proven. We would rather report that honestly than pretend to a certainty the record does not supply.

CANOE: the committee that never sleeps

That shrug matters, because the sea exerts a peculiar gravitational pull on amateur etymology. Word enthusiasts have a running joke about it: CANOE, the Committee to Ascribe a Naval Origin to Everything. It is a joke with teeth, because the pattern is real. A nautical story is vivid, faintly heroic and satisfyingly concrete — real ropes, real posts, real weather — and a vivid story spreads faster than a dull true one. Once “port out, starboard home” or “let the cat out of the bag” (the cat-o’-nine-tails, supposedly) is loose, no amount of correction quite reels it back in.

So a short list of expressions that get a naval commission they have not earned:

• “Toe the line” is regularly explained by sailors standing to attention along the seams of the deck planking. The trouble is that the phrase is far better attested in the worlds of foot-racing and Parliament, where competitors and members literally lined up at a marked line. The deck-seam story is decoration.
• “The whole nine yards” is confidently traced to the length of a Spitfire’s ammunition belt, or a ship’s sails, or any number of maritime and military measures. None survives contact with the evidence: the earliest citations are American, early twentieth century, and nothing to do with the sea.
• “Posh” — “port out, starboard home,” the cool cabins of the India run — is the most famous nautical acronym of all, and it is false; the story cannot be found before the 1930s, well after the word was in use.
• “A square meal” is routinely said to come from the square wooden platters on which the Royal Navy served food. The Oxford English Dictionary finds no naval connection at all: the phrase is American, and surfaces among miners and frontier eating-houses long after those platters were in use. The square plate is a prop bolted on afterwards.
• “To let the cat out of the bag” is often tied to the cat-o’-nine-tails whip drawn from its bag before a flogging. There is no evidence for it. The phrase’s earliest print appearance dates only to around 1760, and honestly its origin is simply unknown — which has not stopped the naval story from being repeated as fact for two centuries.

The genuine harvest

None of this diminishes the real inheritance, which is large. To “batten down the hatches” is to secure a ship’s hatch covers with battens before heavy weather, and it survives, intact and useful, for any coming storm literal or otherwise. To be “high and dry” is the condition of a vessel left by the falling tide, stranded above the waterline. A “loose cannon” — an unsecured gun rolling lethally across a heaving deck — is a metaphor so exact that it has outlived the ships of the line entirely. And the humble log of a ship’s speed, thrown overboard on a knotted line, gave us both the “knot” as a unit and the “logbook” that recorded it, and thence the “blog” you may well be reading this on.

One genuine survivor deserves special mention precisely because it no longer looks nautical at all. To describe someone as “aloof” is to reach, unknowingly, for a helm order. The word comes from a-luff — “to the luff,” the windward side — an instruction to bring the ship’s head up into the wind and so hold her off a hazardous shore. To keep aloof was to keep a wary, deliberate distance, and the sense of chilly detachment grew straight out of that manoeuvre. It is the perfect illustration of the rule: the phrases with the strongest nautical claim are often the ones that have travelled furthest from the water, while the ones that still sound saltiest — the square platters, the whip in the bag — are frequently the impostors. Where the trail through the old sea-manuals is real, we follow it gladly; where it is only a good yarn, we say so.

The lesson the sea teaches, then, is a double one. English really does owe an enormous debt to sailors, whose need for precision under pressure minted metaphors we now use without a thought. But the very appeal of that story is a trap, and the mariners themselves would appreciate the point: check your bearings, sound the depth, and do not assume that because a phrase sounds like the sea it actually came from there. The honest answer for “the bitter end” is “probably nautical, not certainly.” That is less romantic than a firm verdict, and a good deal truer.
