shaped like a circle or disk
Having a round, circle-like shape.
用法模式：
a circular [object]
常见错误：
Learners sometimes use "circle" instead of "circular" before a noun, saying *a circle table* instead of *a circular table*. Use "circular" to describe the shape of the noun and "a circle" when the noun itself is the shape, as in *draw a circle*.
近义词
round (More general and common; can also describe spheres or vague roundness, not only flat circle shapes.)
反义词

moving or arranged in a circle
Going in or making a round path, not straight.
用法模式：
a circular [route / path / movement]

近义词
roundabout (Often suggests an unnecessarily long or indirect route; "circular" is more neutral and geometric.)

using faulty self‑supporting logic
Describing an argument that is bad because it uses its own conclusion as a reason to believe that conclusion.
用法模式：
a circular [argument / explanation / definition]
常见错误：
Learners sometimes confuse "circular" with "cycle" or "cyclical" and think it only means "repeated many times". In logic, a "circular argument" is wrong because it uses its own conclusion as a reason, not just because the discussion goes in circles.
近义词
self‑referential (Focuses on referring to itself; "circular" specifically emphasizes faulty logical structure.)
反义词
logical (Describes reasoning that follows valid rules and does not rely on its own conclusion as proof.)

operating in a closed, repeating cycle
Describing a system where things go in a loop and are used again instead of being thrown away or stopped.
用法模式：
a circular [process / system / model / economy]
常见错误：
Learners sometimes think "circular economy" means an economy that goes around in circles without progress. Here, "circular" refers to materials and products being reused and recycled in a loop, in contrast to a "linear" model of take‑make‑waste.
近义词
cyclical (Emphasizes regular repeating cycles; "circular" often highlights closed loops and reuse, especially in economics and sustainability.)
反义词
linear (Describes a one‑way process moving from start to end without looping back or reusing outputs.)

letter or notice sent widely
A paper or email message that is sent to many people at once, usually with the same text.
用法模式：
send a circular to [people / members / customers]
常见错误：
Learners sometimes confuse "circular" (noun) with the adjective and say *send a circular letter paper* instead of simply *send a circular*. As a noun, "a circular" already means a letter or notice sent to many people.
近义词
flyer (Usually an advertising sheet given to the public; not always used for official internal communication like some circulars.)
反义词
personal letter (A message written for one specific person, not a standard text sent to many people.)
