by and large

The popular story

For once, the popular story and the true story are one and the same, and the phrase is a small monument to the age of sail. ‘By and large’ is very often cited as a nautical expression, and in this instance the sailors really can claim it. The interesting part is not whether the origin is nautical — it is — but what the two little words ‘by’ and ‘large’ actually meant on a working ship, because their sailing senses are almost entirely lost to modern ears.

What the record shows

In the vocabulary of sail, a ship sailing by the wind is sailing close to the wind: pointed up as near to the direction the wind is coming from as she can manage while still keeping her sails full. This is demanding sailing, and a vessel that could hold a good course close-hauled was prized. To sail large, by contrast, is to sail with the wind coming from behind or over the quarter, so that the sails fill generously and the ship runs freely. The two terms mark opposite ends of a ship’s relationship with the wind.

A vessel that handled well ‘by and large’ therefore behaved well across the whole range of conditions — both hard on the wind and running before it. From that comes the modern meaning: taking everything together, in all circumstances, on the whole. The phrase is, in effect, a pair of opposites yoked together to mean ‘the lot’ — much as we say ‘the long and the short of it’ or ‘through thick and thin’. Naming the two extremes was a sailor’s shorthand for everything in between.

It is worth stressing how demanding the ‘by’ half was. Sailing close to the wind meant trimming the sails hard and holding a fine line; point too high and the sails would shiver and lose their drive, a state sailors call being ‘in irons’. A ship that could sail well both by and large was thus one that performed under the trickiest and the easiest conditions alike — genuinely all-round seaworthiness, which is why the phrase carried such weight as praise.

The paper trail supports the story from an early date. William Bourne, writing on navigation in his Inventions or Devises of 1578, praises a ship able to ‘saile well both by and large’ — showing the pairing was already a settled phrase among navigators in the 16th century. The Oxford English Dictionary’s oft-quoted early citation comes a little later, from Samuel Sturmy’s The Mariners Magazine of 1669:

Thus you see the ship handled in fair weather and foul, by and learge.

The spelling ‘learge’ is simply a period form of ‘large’. Both quotations are unmistakably nautical and use the phrase in its technical sense, describing how a ship performs under different points of sailing.

The verdict

The entry is marked attested. The nautical origin is not folklore but sober fact: ‘by’ and ‘large’ are real sailing terms for opposite points of sailing, the combination genuinely meant ‘under all conditions’, and the phrase is documented in navigation writing from the 16th and 17th centuries. This is one of the relatively few ‘this comes from sailing’ claims that the evidence fully upholds — a useful reminder that not every nautical origin story is an invention, even though many are.

How it changed

The move from ship to shore was gradual and logical. Once ‘by and large’ carried the shipboard sense of ‘in all conditions, taken together’, it was a short step to the general meaning of ‘considering everything’ or ‘on the whole’. By the 18th century the phrase had come ashore and was being used with no thought of sails at all, to introduce a broad judgement that holds in most respects even if not in every particular.

In the process the technical precision was lost. Modern speakers use ‘by and large’ as a soft generaliser, a way of saying ‘broadly speaking’ while quietly conceding that exceptions exist. The original image of a ship handling well whether close-hauled or running free has faded completely, which is exactly why the phrase so often gets mangled into ‘by in large’ or ‘buy and large’ — versions that make no sense once the sailing logic is gone.

Usage today

Today ‘by and large’ is an everyday qualifier meaning ‘on the whole’, ‘generally’ or ‘in most respects’. It signals that what follows is a fair overall summary rather than an absolute claim, and it usually appears at or near the start of a sentence: ‘By and large, the reforms have worked.’ It is mildly formal but perfectly at home in ordinary speech and writing, and it pairs naturally with an admission that some details do not fit the pattern. Understanding its origin also helps writers keep it in one piece: it is ‘by and large’, two contrasting sailing directions joined by ‘and’, and no other spelling preserves the sense.

The phrase also sits in good company among landlubber survivals of sailing talk. English is full of expressions that began as ships’ business and now pass unnoticed in offices and living rooms — to be ‘taken aback’, to ‘know the ropes’, to give someone ‘leeway’, to be left ‘high and dry’, or ‘three sheets to the wind’. Some of these attributions are shaky, invented later to sound salty; the value of ‘by and large’ is that it is one of the genuine ones, with printed nautical evidence behind it. It is a small but real piece of the age of sail, still doing quiet work in modern prose.

A last practical note: because the phrase makes a broad claim, it is best not to overload it. ‘By and large’ already concedes exceptions, so following it with ‘more or less’ or ‘generally’ as well is redundant. Used once, cleanly, it does its job — telling the reader that the statement holds in the main, while leaving room for the odd wave that breaks the wrong way.
