return to a worse, earlier state
A change back to an older, usually worse way or condition after things had improved.
Padrão de uso:
regression in [something]
Erro comum:
Learners sometimes confuse "regression" with "recession". "Regression" is about going back to a worse or earlier state in general, while "recession" is specifically an economic downturn. They also mix it with "repression", which means controlling or holding back feelings or people by force.
Sinónimos
backsliding (More informal and often used about moral or personal behavior becoming worse again.)
|
relapse (Often used about health, addiction, or bad habits returning after improvement.)
Antónimos
progress (Emphasizes movement toward a better or more advanced state, the opposite of going backward.)
Colocações
social regression
|political regression
|moral regression
|economic regression
|a regression in [performance]
|a serious regression

statistical method linking variables
A math method that shows how one thing (a result) changes when one or more other things change.
Padrão de uso:
perform regression on [data]
Erro comum:
Learners sometimes think "regression" always means going backwards, even in statistics. In this technical sense, it does not mean "becoming worse"; it is simply the name of a method for modeling numerical relationships.
Sinónimos
regression analysis (More explicit technical term; often used interchangeably in statistics and data science.)
Antónimos
classification (In machine learning, contrasts with regression by predicting categories instead of continuous values.)

reverting to childlike behavior
In psychology, when an adult acts or feels like a much younger person because of strong stress or fear.
Padrão de uso:
regression to [an earlier stage]
Erro comum:
Learners may overuse this word for any childish behavior. In psychology, "regression" is specifically a reaction to stress or conflict, not just any kind of immaturity.
Sinónimos
immaturity (Describes childlike behavior in general, but does not specifically refer to a stress-based return to earlier stages.)
Antónimos
maturity (Refers to stable, adult patterns of behavior and emotion, contrasting with a return to childlike patterns.)
Colocações
emotional regression
|childlike regression
|regression to childhood
|regression under stress
|signs of regression

decrease in disease or tumor
In medicine, when a sickness or tumor becomes smaller or less serious.
Padrão de uso:
regression of [a disease or tumor]
Erro comum:
Learners may confuse this medical sense of "regression" with the general idea of things getting worse. In medicine, "regression" usually means the disease is getting better, not worse.
Sinónimos
remission (Often used for cancer or chronic illness becoming less active; sometimes suggests a longer or more stable improvement than "regression".)
Antónimos
progression (Describes a disease becoming more advanced or severe, the opposite of shrinking or improving.)

|partial regression
|complete regression
|regression of symptoms
|regression of the lesion

Padrão de uso:

Sinónimos

Antónimos
bug fix (Refers to correcting an error, which reverses or prevents a regression.)
