断断续续地, 不规则地
in a way that is not continuous or regular
The idiom "off and on" likely originated from the concept of something being turned on or off non-stop, such as a switch or a light. It conveys the idea of sporadic or irregular occurrences, much like the constant activation and deactivation of a switch. This phrase is commonly used in conversations and written language to express the irregular nature of something, highlighting periods of activity followed by periods of inactivity or absence.
