1. describing a group, mixture, or population in which all the parts or members are

1.adjectiveB2
Definition

describing a group, mixture, or population in which all the parts or members are of the same type or nature — for example, a neighbourhood where every family shares a similar income level, or a scientific sample made up of identical cells.

Example

The student body at Westbrook Academy was surprisingly homogenous, with nearly everyone from the same middle-class background.

collocation: homogenous + group noun (student body, population, sample)

The biology professor prepared a homogenous cell culture by growing identical cells in a controlled nutrient solution.

domain: biology (cell culture, tissue sample)

Common collocations
  • homogenous group
  • homogenous population
  • homogenous culture
  • homogenous mixture
  • homogenous sample
  • homogenous society
Synonyms
  • uniform

    emphasizes consistency without variation; more common in everyday language

  • consistent

    focuses on stability across examples rather than identical composition

  • homogeneous

    the standard spelling of the same word; preferred in formal writing

Antonyms
  • diverse

    emphasizes variety of types rather than sameness

  • heterogeneous

    the formal antonym, describing a mix of different elements

Grammar Patterns

be + homogenous

homogenous + noun

Usage Note

This spelling is a non-standard variant of 'homogeneous.' Although common in scientific and informal writing, most style guides and formal contexts prefer the longer form 'homogeneous.' The two words also differ in pronunciation: homogenous /həˈmɒdʒɪnəs/ vs homogeneous /ˌhɒməˈdʒiːniəs/.

Common Mistakes

The research sample was homogenous, but I wrote homogeneous in my report and was corrected.
The research sample was homogeneous, but I wrote homogenous and was corrected.
In academic writing, 'homogeneous' is the standard spelling; 'homogenous' may be flagged as an error.

2. (in technical fields such as biology, chemistry, or anatomy) describing structur

2.adjectiveC1
Definition

(in technical fields such as biology, chemistry, or anatomy) describing structures, organs, or substances that share a common evolutionary origin or a corresponding structural relationship — for example, the forelimb bones of a bat, a whale, and a human, which all evolved from the same ancestral skeletal pattern.

Example

The anatomy lecture showed that forelimbs of bats, whales, and humans are homogenous structures from a shared ancestor.

domain: biology (anatomy, evolutionary structures)

Hamza's research team identified a homogenous gene sequence present in five related fish species, suggesting a conserved evolutionary pathway.

Common collocations
  • homogenous structure
  • homogenous gene
  • homogenous organ
  • homogenous catalyst
Synonyms
  • homologous

    the standard technical term for shared evolutionary origin; preferred in scientific writing

  • corresponding

    broader and less technical, used for similar structural roles

Antonyms
  • heterologous

    describes structures or genes with different evolutionary origins; used in biology

Grammar Patterns

homogenous + noun

be + homogenous + to/with

Usage Note

This sense is restricted to specialised technical writing. In everyday academic English, 'homologous' is far more common for describing shared evolutionary origin. 'Homogenous' in this sense may be considered a non-standard shortening of 'homologous.' Distinguish from sense 1 (SAME KIND), which refers to a mixture being uniform, not to structural correspondence.

Common Mistakes

The team members were homogenous in their political views' (when meaning they shared an origin).
The team members were homogeneous in their political views
For groups of people, use sense 1; sense 2 only applies to biological or chemical structures.

Synonym discussion

Sense: adjective/1

All three words describe a lack of variation within a group, but they differ in scope and formality. 'Homogeneous' (or its non-standard variant 'homogenous') is the most precise term for describing a mixture or population whose parts are identical in kind — it is the standard choice in scientific writing. 'Uniform' is broader and more common in everyday language: a uniform policy applies the same rules everywhere, and a uniform colour covers a surface without patches. 'Consistent' focuses on stability over time or across examples rather than identical composition: a consistent athlete performs at the same level every game, but the athlete is not 'made of identical parts.' In formal academic contexts, use 'homogeneous' for composition and 'consistent' for behaviour or results. For example: 'The researchers ensured a homogeneous sample of participants' versus 'The results were consistent across all three trials.'

Etymology

GreekLatinEnglish

'Homogenous' entered English in the mid-19th century as a back-formation from 'homogeneous.' The longer word comes from the Greek 'homogenēs' ('homos' = same + 'genos' = kind, race), via the Latin 'homogeneus.' The shorter form 'homogenous' arose partly by analogy with words like 'homologous' and because its four-syllable pronunciation was easier in rapid speech. Over time, the similarity to 'homologous' led some technical writers to use 'homogenous' as a synonym for 'homologous' (sense 2), especially in 20th-century biology and chemistry texts.
