Often confused with decomposition meaning “analysis” or “breaking a problem into parts.”

2
being partly or fully decayed
the condition of being rotten or decayed
Модель уживання:
in (a) decomposition; in a state of decomposition
Поширена помилка:
Learners may use decomposition as a countable noun (*a decomposition*) in this sense; it is usually uncountable.
Синоніми

|
putrefaction (More technical and strongly associated with dead tissue.)
Антоніми
freshness (The opposite condition of not being decayed.)

breaking something into smaller parts
dividing something difficult into smaller parts to study it
Модель уживання:
decomposition of [a problem/task/system] (into [parts])
Поширена помилка:
Not used for physical damage; for physical breaking, learners often want “breakage” or “damage.”
Синоніми
breakdown (More common and less formal; can also mean a failure.)
|
analysis (Focuses on studying something, not necessarily splitting it into parts.)
Антоніми
synthesis (Combining parts to form a whole.)

chemical breakdown into simpler substances
a reaction where one chemical becomes simpler chemicals
Модель уживання:
decomposition of [a compound] (into [products])
Поширена помилка:
In chemistry, decomposition is a type of reaction, not just “rotting.”
Синоніми
breakdown (More general; can describe chemical change without naming the reaction type.)
Антоніми
synthesis (A reaction where simpler substances combine to form a compound.)
Словосполучення

representing something as component parts
writing a number or matrix as simpler parts
Модель уживання:
decomposition of [a number/matrix] (into [components])
Поширена помилка:
Often confused with “composition” in math (building a function), which is a different idea.
Синоніми
factorization (Common for numbers/polynomials; one specific type of decomposition.)
|
expansion (General term for rewriting in a sum/series; not always a decomposition.)
Антоніми
composition (Combining simpler mappings or parts to build a more complex object.)

splitting a system into smaller parts to build it
Модель уживання:
decomposition of [a system/project] into [modules/components]
Поширена помилка:
In project management, “decomposition” is not the same as “deadline breakdown”; it means dividing the work into parts.
Синоніми

|
partitioning (More general; can be used in systems, data, or networks.)
Антоніми
