1.nounB2

Example

The police released a composite of the suspect based on descriptions from three witnesses.

police composite — law enforcement usage from multiple witness descriptions

The band's latest album is a composite of jazz, folk, and electronic music.

Common collocations
  • composite sketch
  • digital composite
  • photographic composite
  • composite image
Synonyms
  • mixture

    Less structured; mixture allows parts to blend. Composite implies parts remain distinguishable.

  • compound

    Often implies chemical bonding or fixed proportions; composite is broader and less technical.

  • blend

    Suggests parts fuse into something seamless; composite keeps parts visible.

Antonyms
  • single entity

    A composite is made of parts; a single entity is undivided.

Usage Note

Often used in law enforcement as 'composite sketch' — a picture of a suspect assembled from descriptions given by witnesses.

Common Mistakes

The cake was a composite of flour and sugar.
The cake was a mixture of flour and sugar.
'composite' implies distinct parts that stay recognisable; ingredients that blend evenly are a 'mixture'.

2.nounB2
Definition

A material produced by bonding two or more different substances (such as fibres and resin) to create a product with better strength, lightness, or durability than the individual ingredients alone. Typical uses include aircraft parts, bridge decks, and sports equipment.

Example

The bridge was built using a lightweight composite of carbon fibre and polymer resin.

composite of [substance1] + [substance2] — two-ingredient formula

Many modern aircraft use composites instead of metal to save weight.

Common collocations
  • carbon-fibre composite
  • polymer composite
  • composite panel
  • composite decking
  • lightweight composite
Synonyms
  • compound material

    Nearly synonymous, but more common in scientific contexts.

  • laminate

    Specifically describes layered composites, not all types.

  • reinforced material

    Highlights that one substance strengthens another, a subset of composites.

Antonyms

Usage Note

Common in engineering and manufacturing. Typical examples include fibreglass (glass fibres + resin) and carbon-fibre composites. Do not confuse with 'alloy', which involves metals mixing at the atomic level.

Common Mistakes

Steel is a composite of iron and carbon.
Steel is an alloy of iron and carbon.
'composite' refers to materials where the original substances stay physically separate; 'alloy' is for metals blended at the atomic or molecular level.

Synonym discussion

Sense: noun/1

A composite is formed from distinct parts that remain recognisable within the whole, like a police sketch built from multiple witness accounts. A mixture is any combination where the parts can be physically separated — sand and gravel, for example. A blend suggests the parts lose their individual identity, as in blended tea or blended whiskey, where the original components are no longer distinguishable. A compound typically implies chemical bonding (water is a compound of hydrogen and oxygen) but can also refer to a complex word formed from two roots. An amalgam suggests a smooth, seamless fusion of diverse elements, like an artistic style that borrows from several traditions. In daily use: 'Her painting was a composite of several magazine images' (parts still visible); 'The music is a blend of jazz and rock' (styles merged into one sound).

Etymology

LatinFrenchEnglish

From Latin 'compositus', the past participle of 'componere' (com- 'together' + ponere 'to put'), meaning 'put together'. Entered English via French in the 1400s, originally describing things made of several parts. The engineering sense of a man-made multi-substance material developed in the mid-20th century alongside fibreglass and reinforced plastics.
