present, current

今 is composed of 亼 (gather) and a horizontal stroke. 亼 depicts an open mouth facing downward, while the horizontal stroke represents closure or sealing; thus 今 conveys the idea of closing the mouth, and its original meaning was something held in the mouth (neither spit out nor swallowed), this meaning was later replaced by 含. Since something held in the mouth is neither expelled nor swallowed, it extended to mean the present moment or now, which is the current primary meaning of 今.
