Back-Formation: Words Created by Removing Suffixes

What Is Back-Formation?

Back-formation is a process of word formation in which a new word is created by removing a real or supposed affix (usually a suffix) from an existing word. It is, in essence, the reverse of the normal derivation process. Normally, English creates new words by adding suffixes to base words: "edit" + "-or" = "editor," "donate" + "-ion" = "donation." In back-formation, speakers work backward from the derived form to create a base form that didn't previously exist.

Here's the surprising truth: the verb "edit" was created from the noun "editor," not the other way around. "Editor" came first (borrowed from Latin editor), and English speakers assumed it was formed by adding "-or" to a verb "edit"—so they created the verb "edit" by removing the suffix. Similarly, "donate" was back-formed from "donation," "televise" from "television," and "babysit" from "babysitter." In each case, the apparently simpler, more basic word was actually created after the more complex one.

How Back-Formation Works

Back-formation exploits the patterns and regularities of English word formation. English has highly productive suffix patterns: -er for agent nouns (teacher, worker, driver), -tion/-sion for action nouns (creation, decision, explosion), -ous/-ive for adjectives (dangerous, creative, expensive). Speakers internalize these patterns and can apply them "in reverse."

When a speaker encounters a word like "television" (borrowed as a complete unit from French), they unconsciously analyze it as containing the suffix "-ion" (which turns verbs into nouns: create/creation, decide/decision). By this logic, removing "-ion" should reveal the underlying verb—so "televise" is born. The analysis is historically wrong (the word "television" was coined as a whole from Greek tele- "far" + Latin visio "seeing"), but it's linguistically productive and follows the normal rules of English morphology.

The Role of Analogy

Analogy is the driving force behind back-formation. Speakers identify a pattern in existing word pairs and extend it to new cases:

• If create → creation (verb → noun with -tion), then donation → donate must follow the same pattern.
• If write → writer (verb → agent with -er), then editor → edit must follow the same pattern.
• If observe → observation (verb → noun with -ation), then television → televise must follow the same pattern.

In each case, the analogy is valid as a pattern—the "error" is only in the historical direction of derivation. Once the back-formed word enters general use, it becomes a fully legitimate word indistinguishable from any other.

Classic Examples of Back-Formation

These well-established English words were all created through back-formation, though most speakers today have no idea:

Verbs Created from Nouns

The most common type of back-formation creates verbs from nouns, particularly from agent nouns (nouns ending in -er, -or, -ar) and action nouns (ending in -tion, -sion, -ment):

From Agent Nouns (-er, -or, -ar)

• babysit ← babysitter — the verb was created because people needed a way to describe what babysitters do
• burgle ← burglar — British English; American English tends to use "burglarize" instead
• buttle ← butler — a humorous back-formation, not widely accepted
• edit ← editor — now completely standard
• peddle ← peddler — another case where the agent noun came first
• sculpt ← sculptor — an alternative to the already existing "sculpture" (as a verb)
• swindle ← swindler — borrowed from German Schwindler

From Action Nouns (-tion, -sion, -ment)

• automate ← automation
• donate ← donation
• emote ← emotion
• liaise ← liaison
• orate ← oration
• televise ← television
• resurrect ← resurrection

Verbs and Nouns from Adjectives

Back-formation also creates words from adjectives, though less frequently:

• greed ← greedy — the adjective "greedy" existed centuries before the noun "greed"
• sleaze ← sleazy — the noun was back-formed from the adjective
• grovel ← groveling (the adjective/adverb form came first)
• difficult ← difficulty — although this direction of derivation is debated by some etymologists

The Curious Case of "Pea"

One of the most famous back-formations in English is the word "pea." The original word was "pease" (as in "pease porridge hot"), which was a mass noun like "rice" or "wheat." Over time, speakers reinterpreted the final /-z/ sound as a plural suffix ("-s"), concluded that the singular must be "pea," and created the new singular form by back-formation. Similarly, "cherry" was back-formed from the Old French cherise, where the "-ise" ending was misinterpreted as a plural.

Modern Back-Formations

Back-formation continues to be a productive word-formation process in contemporary English:

• crowdsource ← crowdsourcing (the gerund/noun appeared before the base verb)
• binge-watch ← binge-watching
• hand-sanitize ← hand sanitizer
• proofread ← proofreader (the agent noun slightly predates the verb)
• people-watch ← people-watching
• opt-in / opt-out ← the noun phrases came first in many legal and marketing contexts

The digital age has been particularly fertile for back-formations. As new technologies create new nouns (usually naming things or processes), speakers quickly back-form verbs to describe the actions associated with them. This is a natural and efficient way for language to fill lexical gaps—when you have a noun for the thing, you need a verb for the doing.

Controversial and Contested Back-Formations

Some back-formations are controversial, with usage authorities disagreeing about their acceptability:

• Enthuse (from enthusiasm): First attested in 1827, "enthuse" has been criticized by prescriptivists for over a century. Despite this, it is widely used in informal American English and appears in major dictionaries.
• Orientate (from orientation): Standard in British English but considered redundant in American English, where "orient" is preferred.
• Commentate (from commentator): Some usage guides object, preferring "comment," but it's well established in sports broadcasting.
• Administrate (from administration): Often criticized as unnecessarily long compared to "administer," but used in some professional contexts.
• Conversate (from conversation): Widely used in informal and AAVE (African American Vernacular English) contexts but criticized by some authorities who prefer "converse."

These controversies illustrate an important point: there is no linguistic reason why back-formed words should be any less "valid" than words formed by normal derivation. The resistance to certain back-formations reflects social attitudes about language change and "correctness" rather than any inherent deficiency in the words themselves.

Back-Formation vs. Other Word-Formation Processes

It's useful to distinguish back-formation from related but different word-formation processes:

• Derivation: Adding an affix to a base word to create a new word (happy → happiness). Back-formation is the reverse.
• Clipping: Shortening a word without regard for morphological structure (telephone → phone, examination → exam). Clipping removes any part of the word; back-formation specifically removes a perceived affix.
• Conversion (zero derivation): Using an existing word as a different part of speech without changing its form (the noun "run" → the verb "run"). Back-formation actually changes the word's form.
• Folk etymology: Reshaping a word to resemble familiar morphemes. While related, folk etymology changes a word's form to add familiar elements, whereas back-formation removes elements.
• Blending/Portmanteau: Combining parts of two words (breakfast + lunch = brunch). This is additive, while back-formation is subtractive.

Historical Development of Back-Formation Studies

The concept of back-formation was first identified and named by the Scottish lexicographer James Murray while working on the Oxford English Dictionary in the late 19th century. Murray noticed that certain words appeared to have been derived from longer forms by removing suffixes, contrary to the normal direction of English word formation. He coined the term "back-formation" to describe this process, adding it to the metalanguage of linguistics.

Since Murray's time, back-formation has been recognized as one of the standard word-formation processes in English, studied extensively by morphologists and lexicographers. The OED itself now labels hundreds of words as back-formations, providing detailed etymological notes explaining how each word was created.

Why Back-Formation Matters

Back-formation matters because it demonstrates something profound about how language works: speakers don't just passively receive and transmit words—they actively analyze, decompose, and reconstruct them. When a speaker creates "edit" from "editor," they're demonstrating sophisticated (if unconscious) knowledge of English morphological rules. They understand that "-or" is a suffix, that removing it should reveal a verbal base, and that the resulting form should function as a verb. This is implicit linguistic knowledge of a high order.

Back-formation also shows that language is not static—it is constantly being reshaped by its speakers to meet their communicative needs. When there's a gap in the vocabulary (you have "editor" but no verb for what an editor does), speakers will fill it using whatever word-formation tools are available. Back-formation is one of those tools, and its products have enriched the English vocabulary with hundreds of useful and now-indispensable words.

Understanding back-formation deepens your appreciation of the etymological complexity of English and reminds you that the relationships between words are not always what they seem. The next time you edit a document, donate to charity, or televise an event, you'll know that you're using words that were born not through the normal process of growth, but through the creative reverse-engineering of language by ordinary English speakers.
