magazine or journal issued regularly
A magazine or journal that is printed or put online every week, month, or other regular time.
用法模式：
a periodical on [topic]; an issue of the periodical
常见错误：
Learners sometimes think 'periodical' means 'from time to time' or 'occasional' when used as a noun. As a noun, it almost always means a magazine or journal that comes out regularly. Learners may also incorrectly say *'a science periodical magazine'*; 'periodical' alone already means a magazine or journal, so usually you say 'a science periodical' or 'a science magazine', not both together.

常见错误：
Learners often confuse 'periodical' with 'periodic' and 'regular'. In most modern English, 'periodic' or 'regular' is more common, especially in science or everyday speech, while 'periodical' sounds slightly more formal or old-fashioned. Also, 'periodical' is not used to mean 'sometimes' or 'from time to time'; it implies a fixed or fairly regular pattern.
近义词

regular (More common and less formal; can mean frequent or routine in general, not always strictly at fixed intervals.)
反义词
continuous (Describes something that goes on without a break instead of happening at separate times.)
|
one-time (Describes something that happens only once instead of repeating at intervals.)
