deformation

deformation — noun

1. the process by which an object's original shape or form becomes altered, especia

1.nounB2
Definition

the process by which an object's original shape or form becomes altered, especially by pressure, heat, or damage, so that it no longer looks normal

Example

The metal frame showed clear signs of deformation after the fire weakened its structure.

collocation: show signs of deformation

Doctors noticed a slight deformation in the bone where the old fracture had healed poorly.

collocation: deformation in [body part]

Common collocations
  • plastic deformation
  • elastic deformation
  • permanent deformation
  • structural deformation
  • deformation of the spine
  • skin deformation
  • surface deformation
  • ground deformation
Synonyms
  • distortion

    broader term; can refer to sound, image, or shape; slightly more common in everyday English

  • warping

    more specific to materials like wood or metal caused by heat or moisture

  • bending

    less severe; implies a curve rather than permanent damage

  • twisting

    focuses on rotational or torque-induced shape change

Antonyms
  • formation

    the process of giving something its original shape

  • restoration

    the act of bringing something back to its original shape

Grammar Patterns

deformation + of + noun phrase

deformation + in + noun phrase

undergo/suffer/show + deformation

Usage Note

Common in technical contexts — engineering, medicine, and geology — when describing how materials or body parts lose their proper shape under stress or damage. The countable form (deformations) is used when referring to multiple instances or types of shape change.

Common Mistakes

The metal showed a deformity after the crash.
The metal showed deformation after the crash.
'deformity' describes a lasting undesirable shape (especially of living things), while 'deformation' focuses on the process or result of shape change for objects.

2. a harmful change that makes a system, set of values, or relationship worse than

2.nounC1
Definition

a harmful change that makes a system, set of values, or relationship worse than it was before

Example

Critics argued that the new policy would lead to a deformation of democratic principles.

collocation: deformation of [abstract concept]

The company's culture underwent a gradual deformation as short-term profits became the only goal.

Common collocations
  • moral deformation
  • social deformation
  • deformation of values
  • deformation of truth
  • deformation of justice
  • cultural deformation
Synonyms
  • corruption

    stronger moral judgment; implies deliberate dishonesty or decay

  • distortion

    can be used for both physical and abstract; less severe than 'deformation'

  • perversion

    very strong; suggests twisting something into something unnatural or immoral

deformation + of + abstract noun phrase

Usage Note

Used in formal or critical writing about moral, political, or social change. Carries a strong negative judgment — the speaker considers the change harmful. Distinguish from sense 1 (SHAPE CHANGE): sense 2 applies to abstract systems, not physical objects.

Synonym discussion

Sense: noun/1

All four words describe a change in shape, but they differ in what kind of change is involved. Distortion is the broadest term — it covers any change that makes something look different from how it should, including sound and images (a distorted photograph). Warping is more specific: it usually refers to flat materials like wood, metal, or plastic that become bent or curved by heat or moisture (the door had warped in the rain). Bending suggests a curve or angle that can sometimes be reversed (bending a wire into a circle). Twisting implies a spiral or rotational force applied to an object (twisting a towel to wring out water). Deformation is the most technical term among them and often suggests that the change is permanent or damaging. In everyday speech, you might say 'the frame bent in the wind,' but an engineer would say 'the frame underwent deformation under stress.'

Etymology

LatinOld FrenchEnglish

From Latin 'deformare', meaning 'to take the shape out of something' — formed from 'de-' (removing, taking away) and 'formare' (to shape, to form). The word entered English in the late 15th century through Old French 'deformation'. Originally used for physical disfigurement, it later extended to abstract meanings of moral or social worsening.
