If one goes through the citations in the Milon Even Shoshan, one might see references to words from the Yerushalmi with attribution like this:
Please zoom in and look at the entry for pileish, on the last line of the right column of page 1298. The reference is to ירושלמי סוכה נג ד
The amud is "dalet". I had it explained to me that an early printing of the Yerushalmi was in 4 columns so the citation for amud is to the particular column.
However, I vaguely recall a Yerushalmi in which there were quadrants on the page. I don't know if I am remembering some version of the text described in this question, or it there is another layout of the Yerushalmi using quadrants which specifically explains the aleph-dalet amud references. Does anyone know of a quadrant based layout specifically for the Yerushalmi?
