merism

How to spot it

A merism names a whole by its contrasting parts, the way high and low covers every height in between. "Everything from X to Y" stretches that into a range, and a sentence that opens with it has promised you a span. There is a cheap way to find out whether it has one: name the scale those two endpoints are ends of. Say it in a word if you can, something like price, temperature, difficulty, or the length of a working day. If the scale has a name, the sentence has quietly told you about the middle as well as the ends, which is why anybody reaches for this shape at all. If you cannot name one, there is no middle. You are holding two examples with a preposition wedged between them.

Take a line like "the workshop covered everything from soldering to the ethics of repair." Both of those genuinely happened in that workshop, and the sentence is not lying about anything. It is just not ranging. Soldering is not one end of a workshop and repair ethics is not the other, so naming them implies no third session, and the words carry the same freight that "soldering and ethics" would have carried at a quarter of the length. Compare "symptoms ranged from mild to severe," which names a scale a clinician works with every day and really does report the part nobody bothered to describe.

Two smaller signals, both worth roughly what they cost. Delete the word "everything" and see what survives, because an honest range usually still stands up while a hollow one drops to a list of two. And a writer reaching for a third item never had a range at all. A scale has ends, not stops.

Why models overdo it

Breadth is expensive. A real list means knowing a subject well enough to name its genuine members, and, harder than that, knowing when you have named enough of them and can stop. Implying breadth costs two nouns, and both nouns are usually sitting right there in whatever the sentence was already about.

A model picking its next word is not asking whether a scale exists. It is weighing what tends to follow what, and after "everything from" what tends to follow is a noun, then "to," then another noun. That is nobody's mistake. The construction is common in good prose precisely because good writers earned it, and the weighing has no way to tell them from the writers who did not, since it is not holding a picture of the thing being described. A scale is a picture.

That is why the shape outlives the substance. It still reads as coverage, so it keeps getting written, and past some volume it stops reading as coverage at all. It starts reading as somebody who had two examples and quit.

When it's fine

Often, which is the part a suspicious reader tends to skip. A merism is sound whenever the poles are genuinely poles, and good writers reach for it constantly.

Obama did it on purpose in his first inaugural address, addressing the world from the grandest capitals to the small village where his father was born. The axis is the size of a place. He named its two ends and kept every city and village between them inside the sentence without listing one, because each sits somewhere on the line those ends draw. Take the range out and he is reduced to "everywhere," which claims the same ground and carries none of it.

Twain does the plainer version, a merism of the body, and the price shows more clearly there. White linen from head to foot leaves no part of the man out, because a body has a top and a bottom and nothing else. That is what an honest range costs you: the middle. Say everything from the shallow end to the deep end and you have just claimed the stretch where a child can nearly stand, and a reader may hold you to it. Two examples commit you to nothing. That is why they are easier to write, and why they are worth less once written.

So name the scale before you commit to the range, and write the list if no scale comes. A real list is harder to fake, and readers can usually tell.

Where it comes from

The name comes from the Greek merismos, a dividing, and the habit is older than the name. Hebrew poetry ran on it. Heaven and earth stand for the whole created world, going out and coming in for everything a person does, and a verse in Psalm 113 carries a full day from the rising of the sun to its going down. Name the two ends, mean the whole thing. English handbooks catalogued the figure early, in a wider sense. George Puttenham's 1589 treatise called it the distributor and demonstrated it by breaking one ruined house into its named parts, undermined and beaten down and unfloored and unroofed, and Angel Day's 1599 handbook covers the same ground. That older merismus divides a whole into as many parts as it needs, while the sense most writers mean today is the narrower one, a pair of contrasting parts standing for everything they bound. The paired form outlasted four centuries of changing fashion for one plain reason: the poles it names are the real ends of something a reader can already picture. A day does run from dawn to dusk. A building does run from its foundation to its roof. What has changed is not the figure but the traffic. The shape is now cheap to produce in quantity, and a shape produced in quantity gets used where no scale exists, which is how a device invented to compress a real span ended up marking prose with nothing to compress.
