at AN.v.22 is doubtful reading (variant reading anuyutta). The meaning is either “inferior to, dependent on, a subject of, a vassal” or “attending on”. The explanation may compare Sk. anuyātaṃ attendance, in which latter case anu-yantṛ would be “an inferior ruler” and P. yanta would represent the n. a.g. yantā as a-stem. The variant reading is perhaps preferable as long as other passages with anuyanta are not found (see anuyutta 2).
