Q: I’m seeing “more so” or “moreso” where I would expect “more.” Am I suffering from the usual recency illusion? Can I change it to “more” when editing? I sometimes have trouble knowing whether a language change is far enough along to indulge it.
A: The two-word phrase “more so” is standard English and showed up nearly three centuries ago. You can find it in two of James Madison’s essays in The Federalist Papers and in Jane Austen’s novel Emma.
The one-word version “moreso” has been around for almost two centuries, though it’s not accepted by any modern standard dictionary. The Oxford English Dictionary, an etymological reference, says it’s mainly an American usage.
The OED says “more so” (as well as “moreso”) is derived from the earlier use of “more” with “ellipsis of the word or sentence modified.” That is, it comes from the use of “more” by itself to modify missing words, as in “I found the first act delightful and the second act even more.” (Here “delightful” is missing after “more” but understood.)
The earliest Oxford example for this elliptical “more” usage, which we’ll expand here, is from a Middle English translation of a 13th-century French treatise on morality:
“He ssolde by wel perfect and yblissed ine þise wordle and more ine þe oþre” (“He shall be morally pure and blessed in this world and more in the other”; from Ayenbite of Inwyt, a 1340 translation by the Benedictine monk Michel of Northgate of La Somme des Vices et des Vertus, 1279, by Laurentius Gallus).
Today, the OED says in a December 2002 update to its online third edition, the usage is seen “frequently with anaphoric so” in the phrase “more so (also, chiefly U.S., moreso).” An anaphoric term refers back to a word or words used earlier, as in “I saw the film and so did she.”
The dictionary’s first citation for “more so” is from an early 18th-century treatise by the Irish philosopher George Berkeley: “This is so plain that nothing can be more so” (A Defence of Free-Thinking in Mathematics, 1735). Berkeley, California, was named after the philosopher, who was also the Anglican bishop of Cloyne, Ireland.
The next Oxford example is from a Federalist essay in which Madison discusses the size of districts that choose senators: “Those of Massachusetts are larger than will be necessary for that purpose. And those of New-York still more so” (Federalist No. 57, “The Alleged Tendency of the New Plan to Elevate the Few at the Expense of the Many Considered in Connection with Representation,” Feb. 19, 1788).
In the OED’s citation from Emma, published in 1815, Emma and Mr. Knightley are discussing Harriet’s initial rejection of Mr. Martin: “ ‘I only want to know that Mr. Martin is not very, very bitterly disappointed.’ ‘A man cannot be more so,’ was his short, full answer.”
The one-word version “moreso” soon appeared in both the US and the UK. The earliest British example that we’ve seen is from a clinical lecture on amputation delivered at St. Thomas’s Hospital, London, Nov. 25, 1823:
“In all these cases, it is of infinite importance to be prompt in your decision, moreso almost than in any other cases to be met with in the practice of the profession” (from an 1826 collection of surgical and clinical lectures published by the Lancet).
The earliest American example we’ve found is from an Indiana newspaper: “Cure for the Tooth ache—This is one of the most vexatious of the ills that flesh (or rather nerves) is heir to. The following simple prescription can do no injury, & from actual experiment, we know it to be highly efficacious, moreso than any specific the dread of cold iron ever induced the sufferer to” (Western Sun & General Advertiser, Vincennes, April 29, 1826).
A few months later, the one-word spelling appeared in the published text of a Fourth of July speech at the University of Vermont in Burlington. Here’s the relevant passage from the speech by George W. Benedict, a professor of natural philosophy and chemistry at the university:
“Much has been said of the ingratitude of popular governments. That in those of ancient times, the very individuals to whom they were under the greatest obligations were as liable as others, sometimes apparently moreso, the victims of sudden resentment or the objects of a cold, unfeeling neglect, is doubtless true.”
The OED’s only example for “moreso” is from a late 20th-century book published in Glasgow: “Anyone perceived as being different from society’s norms was a potential target—no-one moreso than the local wise-woman” (Scottish Myths and Customs, 1997, by Carol P. Shaw).
However, the dictionary does have a hyphenated example from the 19th century: “The English servant was dressed like his master, but ‘more-so’ ” (The Golden Butterfly, an 1876 novel by the English writers Walter Besant and Samuel James Rice).
The linguist Arnold Zwicky notes in a May 30, 2005, post on the Language Log that “more” could replace “more so” or “moreso” in all of the OED citations, though the anaphoric versions (those with “so”) may add contrast or emphasis:
“The choice between one variant and the other is a stylistic one. One relevant effect is that, in general, explicit anaphora, as in more so, tends to be seen as more emphatic or contrastive than zero anaphora, as in plain more.”
In the 21st century, people seem to be using the one-word “moreso” in several new nonstandard senses. For example, Zwicky points out that “moreso” is now being used as a simple emphatic version of “more,” without referring back to a word or words used earlier: “alternating more and moreso have been reinterpreted as mere plain and emphatic counterparts, with no necessary anaphoricity.”
Here’s a recent example from an NPR book review of Brynne Rebele-Henry’s Orpheus Girl, an updated version of the myth of Orpheus and Eurydice (Oct. 13, 2019): “Moreso than Hades’s mythic underworld of old, this camp is Actual Hell (and all the trigger warnings that go with that).”
In another innovative reinterpretation, Zwicky says in his 2005 post, “moreso” is being used as a sentence adverb “without any specific standard of comparison implicated.”
It means “moreover” or “furthermore” in this recent sighting on Amazon.com: “Moreso, infants and preschoolers do not have the ability to express feelings of sadness in apt language” (from a description of How to Detect and Help Children Overcome Depression, 2019, by J. T. Mike).
And “moreso” is being used in the sense of “rather” in this example: “Scientist Kirstie Jones-Williams, who will be helping to train and guide the volunteer researchers, says the goal of the program isn’t to create more scientists, but moreso global ambassadors on the dangers of pollution and more” (from a Sept. 25, 2019, report on NBC Connecticut about a trip to Antarctica).
We’ve occasionally seen the two-word “more so” used in such creative ways too, perhaps influenced by the newer uses of “moreso.” The phrase is a sentence adverb meaning “more importantly” in this query about the hip-hop career of the former Pittsburgh Steelers wide receiver Antonio Brown:
“But we have to know, if Brown starts releasing music, will you listen? More so, will you buy it? Let us know” (an item that appeared Oct. 16, 2019, on Instagram from USA Today’s Steelers Wire).
Although lexicographers are undoubtedly aware of the evolution of “moreso” in the 21st century, none of these new senses have made it into either the OED or the 10 standard dictionaries we regularly consult. Webster’s New World, the only standard dictionary to take note of “moreso,” merely labels it a “disputed” spelling of “more so.” The online collaborative Wiktionary say it’s a “nonstandard” spelling of the phrase.
Getting back to your question, are you suffering from the recency illusion? Well, perhaps a bit. The term, coined by Zwicky, refers to the belief that things you recently notice are in fact recent. Yes, the anaphoric use of “more so” and “moreso” has been around for centuries, but “moreso,” with its new senses, seems to have increased in popularity in recent years.
Historically, “moreso” has been relatively rare in relation to “more so,” according to Google’s Ngram viewer, which compares words and phrases in digitized books published through 2008. However, recent searches with the more up-to-date iWeb corpus, a database of 14 billion words from 22 million web pages, suggest that “moreso” sightings may now be on the rise. Here’s what we found: “moreso,” 8,022 hits; “more so,” 107,837.
Should you change “moreso” or “more so” to “more” when editing? That depends.
Since “moreso” isn’t standard English, we’d change it to an appropriate standard term, depending on the sense—“more,” “more so,” “moreover,” “rather,” and so on.
As for “more so,” we’d leave it alone if it’s being used anaphorically. Otherwise, we’d change it to an appropriate standard term.
But as you note in your question, the English language is evolving. If you ask us about this in a few years, we may have a different answer.
