cellular — adjective

1. relating to the tiny structural units that all living things — plants, animals,

1.adjectiveB2
Definition

relating to the tiny structural units that all living things — plants, animals, and humans — are built from.

Example

The biology class examined the cellular structure of a single leaf under a microscope.

attributive: cellular + noun (structure, biology)

Dr. Aiko Yamamoto published a new study on the cellular changes that happen during sleep.

Common collocations
  • cellular biology
  • cellular structure
  • cellular damage
  • cellular level
  • cellular process
  • cellular change
Synonyms
  • biological

    broader — covers all aspects of living organisms, not just the cell level

  • microscopic

    refers to scale rather than biological structure; not interchangeable

Grammar Patterns

cellular + noun

Usage Note

This sense is almost always used attributively (before a noun), especially with scientific terms like 'structure,' 'biology,' 'damage,' 'level,' and 'process.'

2. built from or divided into many small sections or compartments that fit together

2.adjectiveC1
Definition

built from or divided into many small sections or compartments that fit together to create a larger whole.

Example

The old blanket had a cellular pattern of small squares and a soft, bumpy feel.

attributive: cellular pattern (textile)

A cellular prison layout divides the space into many separate units for individual inmates.

collocation: cellular layout / cellular prison

Common collocations
  • cellular pattern
  • cellular layout
  • cellular structure
  • cellular model
  • cellular office
  • cellular prison
Synonyms
  • compartmental

    more specific — emphasises the division into sections; 'compartmental layout'

  • honeycomb

    describes a specific hexagonal pattern of compartments; 'honeycomb structure'

  • segmented

    broader — divided into segments, not necessarily small cells

Antonyms
  • open-plan

    describes a space without internal divisions, opposite of a cellular office layout

  • solid

    without internal compartments; a solid block vs. cellular foam

Grammar Patterns

cellular + noun

Usage Note

This sense is much less common than the biology sense (adj/1) and is mostly found in technical descriptions of materials, textiles, prison layouts, or organisational structures. Do not confuse with the biological meaning — 'cellular structure' in a biology context refers to living cells, while in material science it refers to compartments.

Common Mistakes

The scientist studied the cellular pattern of the foam.' (reader assumes biology).
The engineer analysed the honeycomb pattern of the foam.
'cellular' in the PART sense can cause confusion with the biology sense; use 'honeycomb' or 'compartmental' when clarity matters.

3. relating to a telephone network that sends and receives calls through radio sign

3.adjectiveA2
Definition

relating to a telephone network that sends and receives calls through radio signals rather than through wires connected to individual buildings.

Example

Priya put her cellular phone on silent mode before the meeting started.

attributive: cellular phone

The cellular network went down during the storm, so no one could make calls.

collocation: cellular network

Common collocations
  • cellular phone
  • cellular network
  • cellular signal
  • cellular service
  • cellular data
  • cellular provider
  • cellular tower
Synonyms
  • mobile

    British English term; 'mobile phone' is equivalent to 'cellular phone'

  • wireless

    broader — covers any device or connection that doesn't use wires, not just phones

Antonyms
  • landline

    a phone connected by wires to a fixed network; opposite of cellular

  • wired

    requiring physical cables for connection

Grammar Patterns

cellular + noun (phone, network, service, system)

Usage Note

In American English, 'cellular phone' (often shortened to 'cell phone' or just 'cell') is the standard term. British English prefers 'mobile phone' or simply 'mobile.' This adjective sense is always attributive — it comes before a noun like 'phone,' 'network,' or 'service.'

Common Mistakes

I need to charge my cellular.' (treating 'cellular' as a noun in US English).
I need to charge my cell phone.
While 'cellular' can be used as a noun (see noun sense 1), 'cell' or 'cell phone' is much more common in everyday American speech.

Synonym discussion

Sense: adjective/3

These four terms all relate to communication without physical wires, but their usage differs meaningfully. 'Cellular' and 'mobile' are largely interchangeable when describing phones and networks, though 'cellular' is more common in American English and 'mobile' in British English. 'Wireless' is the broadest term — it covers Wi-Fi, Bluetooth, radio, and satellite connections, not just telephone networks. A 'wireless network' might connect your laptop to the internet, while a 'cellular network' specifically refers to the tower-based system for phones. 'Cell phone' (or 'cell' for short) is the everyday American noun for the device itself; 'cellular phone' is its full adjective-plus-noun form. In technical writing, 'mobile device' is preferred for tablets and phones together, while 'cellular' specifically refers to the network infrastructure. For everyday speech: Americans say 'cell phone' or 'cell,' Brits say 'mobile.' For network technology, say 'cellular network' regardless of region.

Etymology

LatinEnglish

'Cellular' comes from the Latin word 'cellula' (meaning 'small room'), which is a diminutive of 'cella' ('storeroom' or 'chamber'). The word entered English in the mid-1700s through biology, where scientists used it to describe the tiny compartments they saw in plant and animal tissue under early microscopes. By the 1800s, the term expanded beyond biology to describe anything divided into small compartments, such as a 'cellular blanket' or 'cellular prison.' In the 20th century, the word took on its modern communication meaning: telephone networks were called 'cellular' because the coverage area is divided into small geographic zones (cells), each served by its own radio transmitter.
