gradual development or advance
A slow, step-by-step change or growth toward a later or better stage.
用法パターン：
the progression of [something]
よくある間違い：
Learners often confuse "progression" with "progress". "Progress" is more common and can be used as a verb ("to progress") or a noun. "Progression" is only a noun and usually sounds more formal, often used with "of" ("the progression of the illness", "the progression of her career"). Avoid saying *"I made a good progression"*; say "I made good progress" instead.

ordered series or sequence
A set of steps, events, or things that come one after another in order.
用法パターン：
a progression of [things or stages]
よくある間違い：
Learners sometimes use "progression" when they only mean a list with no sense of movement or change. For a simple ordered list, "sequence" or "order" is often more natural. Use "progression" when each step moves forward from the last one.
類義語
sequence (Stresses the simple order of items; "progression" more strongly suggests movement or development through the series.)
対義語
jumble (Suggests a confused mix with no clear order, the opposite of an ordered progression.)

worsening course of a disease
The way an illness slowly becomes worse or moves to more parts of the body over time.
用法パターン：
the progression of [disease/condition]
よくある間違い：
Learners may think "progression" is always positive because it looks like "progress". In medical contexts, "progression" is often negative, meaning the illness is getting worse. Do not say *"good progression of the disease"*; instead say "the disease is progressing well" only if you clearly mean treatment is working, or better, "the disease is improving".
類義語
advancement (In medical contexts, often used neutrally or negatively for a disease becoming worse; outside medicine it usually has a positive meaning.)
対義語
remission (Means a disease becomes less severe or seems to disappear, the opposite of continued progression.)

用法パターン：
an [arithmetic/geometric] progression of [numbers]
よくある間違い：

類義語
sequence (A general math term for an ordered list of numbers; "progression" usually means the sequence follows a simple, regular rule.)
