abstract — adjective

1. describing something that is a thought, feeling, or quality rather than an objec

1.adjectiveB2
Definition

describing something that is a thought, feeling, or quality rather than an object you can touch or see, such as love, freedom, or honesty.

Example

Justice is an abstract concept that children find hard to grasp.

abstract + concept (typical noun collocation)

Noa struggles to draw abstract feelings like loneliness or hope.

Common collocations
  • abstract concept
  • abstract idea
  • abstract notion
  • purely abstract
  • highly abstract
Synonyms
  • intangible

    stronger emphasis on cannot-be-touched; often about value or feelings

  • conceptual

    more academic; stresses being part of a system of ideas

  • theoretical

    leans toward unproven, planned in the mind only

Antonyms
  • concrete

    things you can touch or point to in the real world

  • tangible

    able to be felt or seen as real

Usage Note

Frequently modifies nouns of thought such as concept, idea, notion, principle. Distinguish from sense 2: this sense contrasts an idea with a physical object, while sense 2 contrasts general theory with specific cases.

Common Mistakes

The chair is abstract because it is wooden.
Beauty is abstract because you cannot hold it.
abstract things have no physical form, so a real chair cannot be abstract.

2. talking about a subject only in general or theoretical terms, without using real

2.adjectiveC1
Definition

talking about a subject only in general or theoretical terms, without using real examples or describing what would actually happen in practice.

Example

Their debate stayed abstract and never touched on what to do tomorrow.

stay/remain + abstract (predicative use)

Viraj prefers concrete cases to abstract arguments about ethics.

contrast: abstract vs concrete arguments

Common collocations
  • abstract argument
  • abstract discussion
  • in the abstract
  • on an abstract level
  • remain abstract
Synonyms
  • theoretical

    stronger link to academic theory; less negative

  • general

    milder; simply not specific

  • hypothetical

    based on imagined situations rather than real ones

Antonyms
  • concrete

    based on real cases and clear details

  • practical

    focused on what works in real life

Usage Note

Often paired with 'concrete' or 'practical' as the contrasting term. Distinguish from sense 1: a discussion about chairs can be 'abstract' in this sense (general, not about any one chair), even though chairs themselves are concrete objects.

Common Mistakes

Show me an abstract example of a real customer.
Show me a concrete example of a real customer.
'abstract' here means without real examples, so an abstract example is a contradiction.

3. relating to broad ideas treated on their own, separated from any single real cas

3.adjectiveC1
Definition

relating to broad ideas treated on their own, separated from any single real case where they might apply — used mainly in the fixed phrase 'in the abstract'.

Example

Freedom sounds wonderful in the abstract, but it brings hard duties too.

fixed phrase: in the abstract

It is easy to love humanity in the abstract and dislike your neighbours.

fixed phrase: in the abstract

Common collocations
  • in the abstract
  • love something in the abstract
  • discuss in the abstract
Synonyms
  • in principle

    phrase; means in theory rather than in real life

  • in theory

    phrase; emphasises the gap between idea and practice

Antonyms

Usage Note

Almost always appears in the set phrase 'in the abstract'. Outside this phrase, prefer sense 2 ('abstract argument'). Distinguish from sense 2: sense 2 modifies the discussion itself; sense 3 frames whether the topic is being treated in isolation from real life.

Common Mistakes

I bought an abstract for my house.
I value privacy in the abstract.
this sense is locked to the phrase 'in the abstract'; do not use it like a normal adjective before a noun.

4. describing visual art — paintings, drawings, or sculptures — that explores shape

4.adjectiveB2
Definition

describing visual art — paintings, drawings, or sculptures — that explores shape, line, and colour for their own beauty or feeling, instead of copying the look of real people, places, or things.

Example

The gallery on Park Street shows abstract paintings full of bold red shapes.

abstract + painting (typical art collocation)

Her grandmother carves small abstract sculptures from pieces of olive wood.

Common collocations
  • abstract art
  • abstract painting
  • abstract sculpture
  • abstract expressionism
  • purely abstract
Synonyms
Antonyms

Usage Note

Common collocations: abstract art, abstract painting, abstract sculpture, abstract expressionism. Often contrasted with 'figurative' or 'representational' art rather than with 'concrete'.

Common Mistakes

The photo of my dog is an abstract painting.
The painting of swirling shapes is abstract.
a realistic image of a real dog is figurative, not abstract.

Sense: adjective/1

All four words describe things that exist in the mind rather than the physical world, but they highlight different aspects. 'Abstract' is the broadest learner-facing choice and contrasts directly with 'concrete' — an abstract idea has no physical form (love, justice, beauty). 'Intangible' overlaps strongly but stresses that something cannot be touched, weighed, or counted; it is common in business contexts ('intangible assets', 'intangible benefits'). 'Conceptual' is more academic and frames an idea as part of a system of thought, often in design or research ('a conceptual framework', 'a conceptual error'). 'Theoretical' tilts toward unproven or untested ideas — useful in science but often hinting that the idea has not yet met the real world. Compare: 'Freedom is an abstract value' (general feel), 'Goodwill is an intangible asset' (financial), 'Her conceptual model needs more data' (academic), 'A theoretical risk that never appears in practice' (untested).

Etymology

LatinOld FrenchMiddle EnglishModern English

Abstract reached English in the late 14th century from Latin 'abstractus', the past participle of 'abstrahere', meaning to draw or pull away (ab- 'away' + trahere 'to drag, pull'). It first described thoughts that had been mentally pulled away from real objects, giving us the philosophy and adjective senses. The art-style sense is much younger, appearing in the early 20th century with painters like Kandinsky who pulled colour and shape away from realistic subjects. The verb senses for summarizing a text and for secretive taking both build on the same core image of 'pulling something out' from a larger whole.
