1.adjectiveC1

Example

adaptive + person noun describing flexible behaviour

The new car has adaptive headlights that turn with the steering wheel at night.

adaptive + product feature noun

Common collocations
  • adaptive learning
  • adaptive technology
  • adaptive behaviour
  • highly adaptive
  • adaptive management
Synonyms
  • adaptable

    more common when describing people; 'adaptive' leans toward systems, technology, or methods

  • flexible

    broader, can mean willing to change plans; 'adaptive' implies actively responding to feedback

  • responsive

    stresses reaction speed; 'adaptive' adds the idea of learning or improving over time

Antonyms
  • rigid

    refuses to change methods even when conditions shift

  • inflexible

    broader; cannot or will not be adjusted

Grammar Patterns

adaptive + noun

be adaptive to + noun

Usage Note

Frequently modifies system or design nouns (software, learning, control, headlights), or abstract nouns about behaviour (thinking, approach, leadership). Distinguish from sense 2: this everyday sense is about quick, intentional adjustments, while sense 2 describes slow biological change across generations.

Common Mistakes

She is very adaptive at cooking new recipes.
She is very adaptable at cooking new recipes.
for describing a person who copes well with new tasks, native speakers usually pick 'adaptable'; 'adaptive' more often modifies systems, designs, or behaviour.

2.adjectiveC2
Definition

in biology, used to describe a body part, behaviour, or trait that has slowly developed over many generations because it helps a plant or animal stay alive in its surroundings — for example, the thick fur of a polar bear or the long beak of a hummingbird.

Example

The snow leopard's thick fur is an adaptive trait that traps body heat.

adaptive trait — biology collocation

Dr. Sven studies the adaptive value of bright colours on tropical frogs.

adaptive value — common in evolutionary biology

Common collocations
  • adaptive trait
  • adaptive feature
  • adaptive advantage
  • adaptive radiation
  • adaptive response
Synonyms
  • evolutionary

    broader; covers any change shaped by natural selection, not just helpful ones

  • advantageous

    general benefit term; 'adaptive' specifically links the benefit to surviving in an environment

Antonyms
  • maladaptive

    trait that lowers, rather than raises, chances of survival

Grammar Patterns

adaptive + biological noun

Usage Note

Common in biology and evolutionary science writing; pairs almost exclusively with nouns like trait, feature, advantage, value, response, radiation. Distinguish from sense 1: changes here happen across many generations through natural selection, not within one lifetime.

Common Mistakes

My cat learned to open doors, which is an adaptive trait.
My cat learned to open doors, which is adaptive behaviour.
in biology, 'adaptive trait' refers to features inherited through evolution, not skills one animal picks up during its life.

Synonym discussion

Sense: adjective/1

All four words describe the ability to handle change, but they differ in subject and emphasis. 'Adaptable' is the everyday word for people and animals — say 'My grandmother is very adaptable' when she settles into new homes easily. 'Adaptive' usually goes with systems, designs, or methods that adjust automatically: 'adaptive cruise control', 'adaptive learning software'. 'Flexible' is the broadest — it covers schedules, rules, and personalities ('flexible working hours'), without implying any feedback loop. 'Responsive' stresses speed of reaction; a responsive website loads quickly when you tap, but it does not necessarily learn from you. Choose 'adaptive' when something improves itself by using new information, 'adaptable' for people who cope well, 'flexible' for plans that bend, and 'responsive' when reaction time is the point.

Etymology

LatinFrenchEnglish

Built in the early 1800s from the verb 'adapt' plus the suffix '-ive', which turns verbs into adjectives meaning 'tending to do the action'. 'Adapt' itself came into English in the 1600s from French 'adapter' and Latin 'adaptare', made of 'ad-' (to) and 'aptare' (to fit). So 'adaptive' literally means 'tending to fit itself to'. The biology sense, linked to Darwin's ideas about natural selection, became common in scientific writing in the late nineteenth century.
