1.adjectiveB2
Definition

of a character, story, or artistic work, having enough complexity and depth to feel genuine and not shallow.

Example

Sayaka's novel has a richly dimensional heroine who feels like someone you might know.

adverb + dimensional + noun: richly dimensional heroine

Mei-Lin called the film a richly dimensional story, with characters facing real moral choices.

Common collocations
  • richly dimensional
  • deeply dimensional
  • fully dimensional
  • dimensional character
  • dimensional portrait
Synonyms
  • multi-faceted

    more common in general usage; less tied to artistic evaluation

  • complex

    broader, covering any kind of complication, not specifically depth

  • deep

    shorter and more colloquial; 'dimensional' is more formal

Antonyms
  • shallow

    describes characters or stories that lack depth

  • one-dimensional

    direct antonym, often used figuratively for flat or simple characters

Grammar Patterns

adverb + dimensional + noun

dimensional + noun (character, plot, portrait, work)

Usage Note

Often used in reviews of books, films, or plays to praise the depth of characters or storytelling. Suitable adverbs before 'dimensional' include 'richly', 'fully', 'deeply', and 'wonderfully'.

Common Mistakes

The character is dimensional.
The character is richly dimensional.
'dimensional' alone in this sense sounds incomplete; pair it with an adverb like 'richly' or 'deeply'.

2. physically occupying space in three directions, so that an object is solid rathe

2.adjectiveB1
Definition

physically occupying space in three directions, so that an object is solid rather than flat like a sheet of paper.

Example

The clay sculpture is fully dimensional, with height, width, and depth you can walk around.

collocation: dimensional + sculpture / model / object

Engineers use special software to turn flat sketches into fully dimensional solid models.

Common collocations
  • fully dimensional
  • dimensional model
  • dimensional object
  • dimensional shape
  • dimensional design
Synonyms
  • solid

    more general; 'solid' does not specifically imply three spatial dimensions

  • three-dimensional

    the full compound form; more precise than 'dimensional' alone

  • spatial

    relates to space in a broader sense; less common for describing objects

Antonyms
  • flat

    describes something that has only length and width but no depth

  • two-dimensional

    precise antonym describing something limited to height and width only

Grammar Patterns

dimensional + noun (object, shape, model, sculpture, image)

three-dimensional / 3D + noun

Usage Note

Often shortened to '3D' in everyday speech. Frequently paired with 'three-' to form 'three-dimensional', which is the standard term for objects that are not flat.

3. used to describe the measured size of an object, especially its length, width, a

3.adjectiveB2
Definition

used to describe the measured size of an object, especially its length, width, and depth when these are expressed in numbers.

Example

The engineer recorded the dimensional specifications of each metal part before assembly.

collocation: dimensional + specification / measurement / analysis / drawing

Christopher checked the dimensional measurements of the oak boards before starting the saw.

Common collocations
  • dimensional measurement
  • dimensional analysis
  • dimensional specification
  • dimensional drawing
  • dimensional data
Synonyms
  • measurement

    noun form; 'dimensional' is the adjective equivalent

  • metric

    focuses on the system of measurement rather than size itself

  • size-related

    less formal, more general

Grammar Patterns

dimensional + noun (measurement, analysis, specification, drawing, data)

Usage Note

Primarily appears in technical, engineering, and scientific contexts. Almost always used attributively (before a noun) and rarely stands alone as a predicate adjective.

Common Mistakes

The dimensional of the box is 30 cm.
The dimensional specifications of the box are 30 cm × 20 cm × 10 cm.
'dimensional' is an adjective, not a noun; pair it with a noun like 'specifications' or 'measurements'.

4. used after a number or prefix like 'multi-' to indicate how many dimensions an o

4.adjectiveB2
Definition

used after a number or prefix like 'multi-' to indicate how many dimensions an object, space, or coordinate system has.

Example

The movie is shown in three-dimensional format, so audience members need special glasses.

suffix pattern: [number]-dimensional

The designer started with a two-dimensional sketch on paper before building the full 3D model.

Common collocations
  • three-dimensional
  • two-dimensional
  • multi-dimensional
  • four-dimensional
  • one-dimensional

Grammar Patterns

[number]-dimensional + noun

[number]-dimensional (used predicatively)

Usage Note

Almost always appears as part of a compound adjective. The number or prefix (two-, three-, four-, multi-) is attached to 'dimensional' with a hyphen. 'Three-dimensional' is by far the most common form.

Common Mistakes

A three dimensional object.
A three-dimensional object.
When used as a compound adjective before a noun, include a hyphen between the number and 'dimensional'.

Synonym discussion

Sense: adjective/2

All four words relate to occupying or describing space, but they differ in specificity and context. 'Dimensional' (sense 2) highlights having height, width, and depth — it is often paired with 'three-' to form the precise compound 'three-dimensional'. 'Solid' is broader: it can mean firm and dense rather than hollow (e.g. 'a solid ball of metal') without necessarily emphasising three spatial axes. 'Spatial' is a more abstract term referring to the nature of space itself (e.g. 'spatial awareness') rather than concrete objects. 'Three-dimensional' is the most precise and widely understood term for something with measurable depth. For everyday objects, say 'three-dimensional puzzle' or '3D model'; for scientific or engineering contexts, 'dimensional analysis' or 'dimensional specifications' are the standard phrases.

Etymology

LatinFrenchEnglish

The word 'dimension' comes from Latin 'dimensio' (a measuring), formed from 'dimetiri' (to measure out), which combines 'dis-' (apart) and 'metiri' (to measure). The adjective 'dimensional' emerged in English in the 1600s as a straightforward derivation from 'dimension', originally used to describe anything relating to measurable extent. The figurative sense (praising complexity and depth in art or character) developed in the 1900s as a metaphor drawn from the physical meaning.
