可以想成一件件事擠在一起、中間幾乎沒有空隙。它的拉丁字根 frequens 本來就是「擁擠、塞滿」的意思；frequent 的畫面比較像同一件事一再回來，一次接一次，把時間排得滿滿的。From the word’s history
From Latin frequens 'crowded, packed, populous'. Both English senses grow from that crowding: events crowded together in time (happening often), and a place you keep filling with your presence (going there often).
源自拉丁文 frequens「擁擠、塞滿、人多」。兩個英文意思都從「擠」長出來：一種是事情在時間上擠在一起（常常發生），一種是你一次次把某個地方塞滿你的身影（常去那裡）。
