transitive: assemble + [furniture] + from [package]

The toy comes with clear pictures showing children how to assemble the rocket.

common collocation: how to assemble + [object]

Common collocations
  • assemble a bookshelf
  • assemble the parts
  • easy to assemble
  • fully assembled
  • assemble according to the instructions
Synonyms
  • build

    broader; can include creating from raw materials, not only joining ready-made parts.

  • construct

    more formal; often for larger structures like buildings or bridges.

  • put together

    everyday equivalent; less formal than 'assemble'.

Antonyms
  • dismantle

    to take a built object apart, often carefully and with the option of rebuilding.

  • disassemble

    direct opposite; to separate something back into its component parts.

Grammar Patterns

assemble + [object made of parts]

assemble + [object] + from/out of [components]

Usage Note

Object is a physical item that has separate parts (furniture, electronics, toys, vehicles, weapons). Often passive in instructions: 'should be assembled by an adult'. Distinguish from sense 2 (gather people): this sense never takes humans as the direct object.

Common Mistakes

I assembled the soup from vegetables.
I made the soup with vegetables.
'assemble' is for joining solid parts that fit together, not for cooking or mixing.
She assembled her essay last night.
She put her essay together last night.
for written or abstract work, 'put together' or 'compose' is more natural.

2.verbtransitive / intransitiveC1
Definition

When people assemble, they gather in one place, usually for a planned reason such as a meeting, ceremony, or protest; you can also assemble a group, summoning them to gather.

Example

Hundreds of students assembled outside the library to protest the tuition rise.

intransitive: people + assemble + in/at [place] + for [purpose]

Mr. Yamada assembled the team in the boardroom to share the merger news.

transitive: subject assembles + group + in [place]

Common collocations
  • assemble a team
  • assemble a crowd
  • assemble in the hall
  • assemble for a meeting
  • assemble outside the building
Synonyms
  • gather

    more general and less formal; works for casual or planned meetings.

    to move quickly away from a central point, often in panic.

Grammar Patterns

assemble + in/at [place]

assemble + [group of people/things]

Usage Note

More formal than 'gather' or 'get together'. Subjects are usually plural humans (crowds, troops, delegates) or, when transitive, an authority figure who summons a group. Distinguish from sense 1: this sense never takes a physical object made of parts.

Common Mistakes

My friends and I assembled at the cafe to chat.
My friends and I met at the cafe to chat.
'assemble' sounds too formal for a casual hangout; use 'meet' or 'get together'.

'assemble' takes the people themselves as object, not the event.

Synonym discussion

Sense: verb/1

All four verbs describe creating a finished object, but they differ in scope and register. 'Assemble' is the most specific: it means joining ready-made parts in the right order, like a flat-pack desk or a model plane — the pieces already exist, and the work is in the connecting. 'Build' is the broadest, covering everything from raising a house with bricks to creating software; the maker may also create the parts. 'Construct' is more formal and is preferred for larger or planned structures (a bridge, an argument). 'Put together' is the everyday spoken equivalent of assemble, and stretches more easily to abstract things like a presentation or a band. So you assemble an IKEA chair, build a treehouse, construct a stadium, and put together a quick playlist.

Etymology

LatinLate LatinOld FrenchMiddle EnglishEnglish

Assemble entered English in the 14th century from Old French 'assembler', which came from the Late Latin 'assimulare', meaning to bring together. The Latin form combines 'ad-' (toward) with 'simul' (together), the same root that gave English 'similar' and 'simultaneous'. The earliest English use was about people coming together for meetings or battles; the meaning of joining mechanical parts grew much later, with the rise of factories and self-build products in the 19th and 20th centuries.
