טעות נפוצה:
Often confused with decomposition meaning “analysis” or “breaking a problem into parts.”
מילים נרדפות
decay (More general and common; less scientific.) | rotting (More informal and vivid.)
הפכים
preservation (Keeping something from decaying.)
צירופים
organic decomposition |natural decomposition |rapid decomposition |slow decomposition |the decomposition of leaves |the decomposition of wood |the decomposition of waste |decomposition in soil |decomposition in water |decomposition occurs

being partly or fully decayed

the condition of being rotten or decayed

תבנית שימוש: in (a) decomposition; in a state of decomposition
טעות נפוצה:
Learners may use decomposition as a countable noun (*a decomposition*) in this sense; it is usually uncountable.
מילים נרדפות
decay (Broader; not as specific to post-death contexts.) | putrefaction (More technical and strongly associated with dead tissue.)
הפכים
freshness (The opposite condition of not being decayed.)
צירופים

breaking something into smaller parts

dividing something difficult into smaller parts to study it

תבנית שימוש: decomposition of [a problem/task/system] (into [parts])
טעות נפוצה:
Not used for physical damage; for physical breaking, learners often want “breakage” or “damage.”
מילים נרדפות
breakdown (More common and less formal; can also mean a failure.) | analysis (Focuses on studying something, not necessarily splitting it into parts.)
הפכים
synthesis (Combining parts to form a whole.)
צירופים
problem decomposition |task decomposition |decomposition into parts |decomposition into steps |logical decomposition |step-by-step decomposition |decomposition of an argument |decomposition of a process |functional decomposition |decomposition approach
נושאים
education |work |problem_solving
דוגמאות

תבנית שימוש: decomposition of [a compound] (into [products])
טעות נפוצה:
In chemistry, decomposition is a type of reaction, not just “rotting.”
מילים נרדפות
breakdown (More general; can describe chemical change without naming the reaction type.)
הפכים
synthesis (A reaction where simpler substances combine to form a compound.)
צירופים
chemical decomposition |thermal decomposition |photochemical decomposition |decomposition reaction |decomposition products |decomposition temperature |catalytic decomposition |decomposition pathway |decomposition occurs |undergo decomposition
נושאים
science |chemistry |education

representing something as component parts

writing a number or matrix as simpler parts

תבנית שימוש: decomposition of [a number/matrix] (into [components])
טעות נפוצה:
Often confused with “composition” in math (building a function), which is a different idea.
מילים נרדפות
factorization (Common for numbers/polynomials; one specific type of decomposition.) | expansion (General term for rewriting in a sum/series; not always a decomposition.)
הפכים
composition (Combining simpler mappings or parts to build a more complex object.)
צירופים
prime decomposition |matrix decomposition |factor decomposition |spectral decomposition |decomposition into factors |decomposition into eigenvalues |decomposition theorem |a decomposition method |unique decomposition |orthogonal decomposition
נושאים
math |education |technology
דוגמאות
  • Prime decomposition expresses a number as a product of primes.

dividing a system into modules

splitting a system into smaller parts to build it

תבנית שימוש: decomposition of [a system/project] into [modules/components]
טעות נפוצה:
In project management, “decomposition” is not the same as “deadline breakdown”; it means dividing the work into parts.
מילים נרדפות
modularization (Emphasizes designing as modules; common in software.) | partitioning (More general; can be used in systems, data, or networks.)
הפכים
integration (Putting separate parts together into a unified system.)
צירופים
functional decomposition |system decomposition |module decomposition |architectural decomposition |decomposition into components |decomposition into services |top-down decomposition |design decomposition |decomposition strategy |decomposition diagram
נושאים
