Yanti is 3rd plural present of yā: see yāti. Note: At D II 269 we should combine yanti with preceding visamā and sambādhā, thus forming denominative verbs: visamāyanti "become uneven" and sambādhāyanti "become oppressed or tight." The translation D.B. II 305 gives just the opposite by reading incorrectly.
(pr, pr 3rd pl of yāti) they go Construction: yā + nti
