movement of blood in the body
The way blood moves again and again around the body.
Mẫu sử dụng:
[someone] has [good/poor] circulation

Từ đồng nghĩa
blood flow (A more everyday term that focuses on the movement of blood, without the medical feel of “circulation.”)
Từ trái nghĩa
stagnation (Describes blood not moving properly, the opposite of healthy circulation.)

The way air, water, or another liquid or gas moves around in a place again and again.
Mẫu sử dụng:

spread of information or items
The way information, papers, or things go from one person to another in a group.
Mẫu sử dụng:
the circulation of [information/document/rumor]
Lỗi thường gặp:
Learners sometimes say “the information is circulating” when they want to emphasize its general presence in a group. This is correct, but “in circulation” or “in wide circulation” is often more natural when talking about how common it is.
Từ đồng nghĩa
distribution (Focuses more on the act of giving or sending out, while “circulation” emphasizes ongoing movement within a group.)
Từ trái nghĩa
suppression (If circulation is allowing information to spread, suppression is actively stopping it from spreading.)

money or coins in use
The money that people are using and spending in a country at a given time.
Mẫu sử dụng:

Lỗi thường gặp:
Learners sometimes use “circulation” alone, saying things like *“The circulation increased”* without context. It is more natural to say “the amount of money in circulation increased” or “cash in circulation increased.”
Từ đồng nghĩa

Từ trái nghĩa
withdrawal (When money or coins are removed from use, the opposite of being kept in circulation.)
