The explanation for this character was previously:
Ideogrammic compound (會意): 酋 (“wine”) + 丌 (“table”).
I changed it to this:
Pictogram (象形); derived from the pictogram of a wine cup placed on a table. The upper component representing a wine cup evolved from 酉 in Oracle Bone Script into 酋 in Small Seal Script, with the two dots (丷) above the 酉 component representing overflowing wine. The lower component representing a table evolved from 一 (a simple line) in Oracle Bone script into 丌 (a table with two legs) in Small Seal script. The 丌 component later evolved into 大 in the process of the alteration of Clerical script forms known as 隸變.
