major change in form or nature
A very big change in how something looks, works, or is.
用法パターン：
the transformation of [something] (into [something])
よくある間違い：
Learners sometimes confuse "transformation" with "transition". A "transition" is the process of moving from one state to another, often gradually, while a "transformation" usually suggests a larger, more complete change in form or character. Learners also sometimes say *"do a transformation"*; in natural English we say "undergo a transformation" or "go through a transformation" or "bring about a transformation".

|

|

large planned change in an organization
A big planned change in how a company, industry, or system is organized and works.
用法パターン：
the transformation of [an organization/system] into [something]
よくある間違い：
Learners sometimes use "change" instead of "transformation" in business contexts, but in management and technology writing, "transformation" usually suggests a deeper, more strategic, long-term change than ordinary change. Another mistake is saying *"do a digital transformation"*; natural phrases include "lead a digital transformation", "carry out a digital transformation", or simply "go through digital transformation".
類義語

|
reorganization (Emphasizes changing the arrangement of departments, roles, or processes.)

mathematical mapping from set to set
In math, a rule that changes each number, point, or object into another number, point, or object.
用法パターン：
a transformation from [set/space] to [set/space]
よくある間違い：
Learners sometimes think a mathematical "transformation" must always change the shape or size of an object, but in math a transformation can also leave an object unchanged (for example, the identity transformation). There is also confusion between "transformation" and "translation"; a translation is one specific kind of geometric transformation that only shifts position.
類義語
mapping (Technical; general term for a rule that assigns each element of one set to an element of another set.)
|
function (Very general mathematical term; does not always imply a geometric or structural change.)
|
operator (Used especially when the transformation acts on functions or vectors in a structured way.)
対義語
invariance (Refers to the property of not changing under a transformation; conceptually opposite to the idea of changing objects.)

change in physical state or energy
In science, a change in the state or form of a material or energy.
用法パターン：
the transformation of [substance/energy] into [substance/energy]
よくある間違い：
Learners sometimes call every scientific change a "reaction". In physics, "transformation" is often preferred for changes of state or energy form, while "reaction" is used mainly for chemical changes involving new substances.
類義語
conversion (Common in energy contexts; focuses on changing one form of energy or substance into another.)
|
phase change (Specific to changes between solid, liquid, and gas.)
対義語
stability (In materials science, describes a state where no transformation occurs under given conditions.)

genetic change by foreign DNA
In biology, a change in a cell’s genes that happens when it takes in and uses DNA from outside the cell.
用法パターン：
the transformation of [cells] with [DNA/plasmid]
よくある間違い：
Learners may confuse "transformation" with "mutation". A mutation is a change in DNA that happens inside the cell, while transformation is a change caused by DNA coming from outside the cell. There is also confusion with "transfection"; in many labs, "transformation" is used mainly for bacteria and yeast, while "transfection" is used for animal cells.
類義語
uptake (Refers only to the taking in of DNA, not the full genetic change.)
|
transfection (Overlapping but more often used for introducing nucleic acids into eukaryotic cells in laboratory settings.)
対義語
genetic stability (Describes cells that maintain their original genetic material without such changes.)
