Meanings

Take apart into pieces

verb
mechanical

To take something apart into its separate pieces, or to come apart into those pieces.

Usage

Use disassemble when the parts remain recognizable and could often be inspected, repaired, moved, or put back together.

Examples

  • The mechanic disassembled the engine on the bench.
  • The shelves can disassemble for easier transport.
  • She disassembled the old laptop before recycling it.
  • The watchmaker carefully disassembled the movement.
  • Workers disassembled the stage after the concert.
  • The toy disassembles into six plastic sections.
  • He kept every screw while he disassembled the cabinet.

Common mistakes

Disassemble is not the same as destroying something beyond useful parts.
IncorrectCorrect

She will disassembled the laptop tomorrow. She will disassemble the laptop tomorrow.

Similar words

Convert machine code to assembly

verb
computing
technical
To translate machine code or object code into assembly-language instructions that a programmer can read.

Usage

Use disassemble for machine code becoming assembly language, and use decompile when the target is higher-level source-like code.

Examples

  • The security analyst disassembled the malware sample.
  • A debugger can disassemble the next instruction.
  • The tool disassembles object code into assembly language.
  • Researchers disassembled the firmware to inspect its routines.
  • The binary was disassembled before the exploit was studied.
  • A good disassembler can disassemble code for several architectures.
  • He disassembled the bootloader and annotated each jump.

Common mistakes

Disassemble is narrower than decompile and does not simply mean debug, unpack, or read source code.
IncorrectCorrect
The analyst disassembled the Python source file. The analyst reviewed the Python source file.
The tool decompiled the binary into assembly instructions. The tool disassembled the binary into assembly instructions.
I will disassemble the program to fix the runtime error. I will debug the program to fix the runtime error.

Similar words

Scatter a gathering

verb
social
archaic
To make a gathered group disperse, or for such a group to break up and scatter.

Usage

Use disassemble this way only in historical or deliberately old-fashioned prose, since modern English normally uses disperse or scatter.

Examples

  • The soldiers were ordered to disassemble the unruly crowd.
  • At the bell, the assembly disassembled into the street.
  • The old account says the mob disassembled before dusk.
  • Officials tried to disassemble the gathering without violence.
  • The crowd disassembled when the rain began.
  • The constable’s arrival disassembled the noisy group.
  • In that older sense, disassemble meant to scatter people who had assembled.

Common mistakes

Disassemble for a crowd sounds archaic in ordinary modern writing.
IncorrectCorrect
The police disassembled the protesters downtown. The police dispersed the protesters downtown.
The audience disassembled after the film ended. The audience left after the film ended.
Please disassemble from the lobby. Please clear out from the lobby.
The meeting was disassembled at noon. The meeting was adjourned at noon.

Similar words

Usage

Use disassemble for objects and machinery, for binary code turned into assembly language, and only rarely for crowds or meetings in an old-fashioned sense.

Common mistakes

Disassemble does not mean destroy, debug, or decompile to high-level source code, and the crowd sense is archaic in ordinary modern English.

Etymology

From dis- meaning apart or away plus assemble. The earliest sense was to disperse a gathering, and the now-common take-apart sense developed later.
