Common collocations
  • marginal difference
  • marginal improvement
  • marginal increase
  • marginal cost
  • marginal effect

Synonyms
  • slight

    similar meaning but neutral in tone; a slight improvement is still noticeable

Antonyms

Grammar Patterns

marginal + noun

be + marginal

Usage Note

Frequently appears with nouns denoting measurable quantities (“difference”, “improvement”, “increase”, “change”). Distinguish from sense 6 (barely profitable), where the focus is on financial adequacy rather than size.

Common Mistakes

The improvement was marginal, meaning it was zero.
The improvement was marginal, meaning it was very small but still noticeable.
marginal means barely measurable, not non-existent.

2. appealing to a very small audience and therefore existing outside the central co

2.adjectiveB2
Definition

appealing to a very small audience and therefore existing outside the central concerns or mainstream of a society or field.

Example

The documentary about traditional folk pottery covered a topic so marginal that fewer than two hundred people watched it online.

attributive: marginal topic / marginal interest

Kemi published her research in a marginal journal with only a few hundred readers.

Common collocations
  • marginal topic
  • marginal interest
  • marginal audience
  • marginal issue
  • marginal figure
  • marginal to the debate
Synonyms
  • niche

    more modern and neutral; a niche interest is simply narrow, not necessarily unimportant

  • peripheral

    more formal; suggests something is at the edge of a field or discussion

  • fringe

    often carries a stronger connotation of being outside the mainstream or unusual

Antonyms
  • mainstream

    accepted or followed by most people

  • central

    of primary importance or relevance

Grammar Patterns

marginal + noun

be + marginal + to + noun

Usage Note

Often paired with “to” (be marginal to something) to indicate peripheral relevance. Can carry a slightly dismissive tone — calling a topic marginal suggests it does not deserve wide attention.

Common Mistakes

This is a marginal change, meaning very few people care about it.
This is a marginal topic, meaning very few people care about it.
use “marginal” for interest/relevance, not for change size (which belongs to sense 1).

3.adjectiveB2
Definition

phrase: marginal gains — small improvements that add up

Common collocations

  • seek marginal gains
Synonyms
  • incremental

    describes regular, step-by-step increases; less specific to the “add up over time” concept

  • cumulative

    focuses on the total effect of additions, but not necessarily small ones

Grammar Patterns

marginal gain(s) / marginal improvement(s)

Usage Note

Popularized in British sports by cycling coach Sir Dave Braidford. The phrase “marginal gains” is a fixed expression and commonly appears in business and self-improvement contexts as well.

4. relating to a parliamentary constituency where the leading parties each enjoy ne

4.adjectiveC1
Definition

relating to a parliamentary constituency where the leading parties each enjoy nearly equal backing from voters, so the outcome hinges on a tiny shift in votes.

Common collocations
  • marginal seat

  • hold a marginal
  • target marginals
Synonyms
  • swing seat

    the equivalent US term; also used in British English but less formal

  • battleground seat

    US term; emphasizes the competitive nature of the seat

Antonyms
  • safe seat

    a seat where one party has a large and stable majority

Grammar Patterns

marginal seat / marginal constituency / marginal ward

Usage Note

Common Mistakes

The candidate lost the marginal seat by a landslide.
The candidate lost the marginal seat by only a few hundred votes.
if the result is a landslide, it is not a marginal seat by definition.

6.adjectiveC1
Definition

(of a business, farm, or activity) producing such a low income that it barely covers the costs involved, leaving almost no profit.

Example

Farmers abandoned the marginal land because it could not produce enough crops.

collocation: marginal land — barely fertile enough

The restaurant operated at a marginal profit and struggled to pay its staff on time.

Common collocations
  • marginal land
  • marginal profit
  • marginal soil
  • marginal cost
  • marginal business
  • marginal farm
Synonyms
  • break-even

    describes a situation where income exactly equals costs; marginal is slightly above break-even

  • unprofitable

    stronger; means the activity loses money rather than barely making any

Antonyms
  • profitable

    producing enough income to make a clear gain

  • viable

    capable of being sustained financially

Grammar Patterns

marginal land / marginal profit / be + marginal

Usage Note

Common in agriculture (marginal land = land of poor fertility) and business (marginal profit = profit so thin that a small cost increase creates a loss). Distinguish from sense 1: here the focus is on financial viability, not numerical size.

Common Mistakes

The company made a marginal profit, so it earned millions.
The company made a marginal profit of just 0.2 percent of revenue.
marginal profit means barely any profit, not a small but meaningful amount.

Synonym discussion

Sense: adjective/1

All four words describe something small, but they differ in how small and in what tone. “Slight” is the most neutral: a slight improvement is small but still noticeable and generally positive. “Negligible” is stronger — something so small that it can be ignored or has no practical effect (e.g., “the cost difference was negligible” means it was not worth considering). “Minimal” focuses on the smallest possible amount, often by design or intention (“minimal waste”, “minimal packaging”); it carries a neutral-to-positive tone of efficiency. “Insignificant” adds a judgment of unimportance: it suggests the thing does not matter, not just that it is small (“her role was insignificant” carries a dismissive edge). “Marginal” is distinctive because it evokes a borderline or threshold: a marginal difference is barely above the cutoff where something changes. For example: “The improvement was slight but real” is neutral; “the improvement was marginal” suggests it was just enough to matter but could easily have gone the other way.

Etymology

LatinFrenchEnglish

From Latin “margo” (edge, border), which produced the Late Latin adjective “marginalis” (relating to an edge). French borrowed it as “marginal” before English adopted it in the 16th century, first with the literal meaning “written in a margin.” Over the 18th–19th centuries the word extended figuratively to describe anything “at the edge” of a group, threshold, or economic boundary — giving rise to the modern range of meanings from “very small in effect” to “barely profitable” and “politically uncertain.”
