Common collocations
  • modular furniture
  • modular kitchen
  • modular sofa
  • modular wall panels
  • modular bookshelf
  • modular design
  • modular system
  • modular construction
Synonyms
  • component-based

    more technical; focuses on the design method rather than the user's ability to rearrange

  • sectional

    usually limited to furniture (especially sofas built in matching sections)

  • standardized

    highlights uniform sizing but does not imply the parts can be separated or moved

Antonyms
  • one-piece

    describes furniture or structures made as a single, inseparable unit

  • built-in

    describes something fixed permanently in place, not designed for rearrangement

Grammar Patterns

modular + noun (furniture, system, building)

be + modular

Usage Note

Unlike adjustable (meaning a single object changes shape), modular means the whole is assembled from separable parts that can be reconfigured or replaced individually.

Common Mistakes

I bought a modular fan that folds flat.
I bought a foldable fan that folds flat.
Modular describes objects made of separable standardized parts; foldable describes objects that can be folded into a smaller shape.

Example

The university's modular degree programme lets students build their own study plan.

modular degree programme — qualification built from selectable units

Kofi chose a modular course so he could study part-time and work during the day.

modular course — flexible structure for part-time study

Common collocations
  • modular course
  • modular degree
  • modular programme
  • modular curriculum
  • modular unit
  • modular system of study
Synonyms
  • unit-based

    clearer but less common; emphasizes the division into self-contained segments

  • credit-based

Antonyms

Synonym discussion

Sense: adjective/1

Modular describes anything built from standardized, interchangeable parts that the user can rearrange or expand — the emphasis is on flexibility through separable units. Component-based is more technical and usually refers to software or engineering design rather than furniture or buildings. Sectional is narrower, used almost exclusively for sofas and seating made in matching pieces that lock together; unlike a modular system, sectional parts are typically designed to fit only one arrangement. Standardized focuses on uniform sizing across products but says nothing about whether the parts can be separated or rearranged — a standardized screw, for example, is not modular. Use modular when the key idea is that the user can add, remove, or move individual pieces freely.

Etymology

LatinEnglish

Comes from the Latin word modulus ('a small measure'), which is a smaller form of modus ('measure, manner'). English adopted the mathematical sense in the 19th century, then expanded into architecture and industrial design in the 20th century as factories began producing standardized, interchangeable parts. The educational sense followed later as universities restructured courses into self-contained units.
