from time to time, again and again
Happening from time to time, again and again, but not all the time.
用法パターン：
[someone] periodically [does something]
よくある間違い：
Learners sometimes use "periodically" when they only mean "once" or "very rarely." "Periodically" always suggests that something happens more than once over time. There can also be confusion with "regularly": "regularly" can mean simply "often" or "on a fixed schedule," while "periodically" more clearly suggests separate times with gaps in between, though the exact schedule may or may not be fixed.
類義語

対義語

at fixed or regular intervals
Happening again and again with the same time gap between each time.
用法パターン：
[something] occurs periodically every [time period]
よくある間違い：
Learners may not realize that in scientific, technical, or formal writing, "periodically" usually implies a clear time pattern (for example, every hour or every month). They may also confuse this use with "regularly" when they only mean "often" rather than "on a schedule."
類義語
regularly (Often used in similar technical or formal contexts, but can also simply mean "often"; "periodically" more clearly highlights the idea of repeated intervals.)
|
at regular intervals (A literal phrase that explains the timing pattern; slightly longer and more explicit than "periodically.")
対義語
irregularly (Describes something that does not follow a fixed pattern in time, opposite of occurring at regular intervals.)
|
randomly (Emphasizes a lack of pattern or predictability, the opposite of a regular, repeated schedule.)
