打 (dǎ): While its primary meaning is “to hit” or “to strike,” in this context, it takes on a more abstract function, similar to “to deal with” or “to handle.”
发 (fā): Commonly means “to send out” or “to dispatch.”
时 (shí): Means “time” or “hour.”
间 (jiān): Means “interval” or “space between.”
When combined, 打发 (dǎfā) literally means “to send away” or “to dismiss.” 时间 (shíjiān) is the standard word for “time.” Therefore, 打发时间 (dǎfā shíjiān) vividly translates to “sending time away” or “dismissing time,” a perfect metaphor for making unwanted, empty time go away.
