1
happen again, often repeatedly
To happen again, usually more than once or in a pattern.
用法模式：
for [problem/event] to recur
常见错误：
Learners sometimes use "recur" as a transitive verb, for example *"They recurred the test"*, which is incorrect. "Recur" is intransitive: you say "the test recurred" or "the problem recurred." Many learners also confuse "recur" with "reoccur"; both mean "happen again," but "recur" is more common in careful writing, especially for things that happen repeatedly. Spelling mistakes like *"reoccuring"* instead of "recurring" are also frequent.
近义词
repeat (More general and common; can be used transitively or intransitively, while "recur" is intransitive and sounds slightly more formal or technical.)
反义词
stop (If something stops, it does not happen again, which is the opposite of recurring.)

come back into the mind again
When a thought or memory recurs, it comes into your mind again and again.
用法模式：
for [thought/memory] to recur
常见错误：
Learners sometimes miss the mental or emotional focus here and think "recur" must always describe outside events. With this sense, it is used for what happens inside the mind: thoughts, memories, images, and dreams recur.
近义词
return (Often used in phrases like "the thought returns"; slightly more common and basic, while "recur" sounds more formal or literary in this context.)
反义词
fade (A memory or thought that fades becomes weaker and does not come back strongly, which contrasts with something that keeps recurring.)

3
return to a topic or issue
To talk or write about a topic again after leaving it for a time.
用法模式：
recur to [a subject/issue/point]
常见错误：
Learners may try to use "recur" transitively, for example *"She recurs the topic"*. In this formal sense, it is used with "to": you recur to a topic, question, or issue. This usage is formal and not common in everyday speech; most of the time, "return to" or "go back to" is more natural.
近义词
revisit (Common modern verb for returning to a subject; slightly less formal and more frequent than "recur to" in everyday writing.)
反义词
digress (To digress is to move away from the main subject, which is the opposite direction of recurring to it.)

call or define itself again
In math or computer code, for a rule or function to use itself again and again to get the answer.
用法模式：
for [function/algorithm] to recur
常见错误：
Learners sometimes confuse "recur" with general repetition in programming. In technical contexts, "recur" usually means the function or definition directly calls itself (recursion), not just any kind of loop or repeated action.
近义词
iterate (In computing, "iterate" means to repeat steps in a loop; "recur" specifically implies a function or definition calling itself rather than using an external loop.)
反义词
terminate (A recurring (recursive) process continues by calling itself again, whereas a terminating process stops and does not call itself further.)
