davati / duyati / du.neti / dunaati

I've come upon a troublesome word that is used as an example in Kaccaayana:

davati / duyati / du.neti / dunaati

I have been unable to find a definition for it.  One source indicated that
it means "he goes", another suggested "is pained" --two very different, and
conflicting translations.

Does anyone have an authoritative translation for this particular word? 
Sorry, but I've exhausted my own reference materials.

Any comments would be helpful,

Sorry to pester the list --I wouldn't normally ask for a word-definition,
but it does appear in the grammatical literature, and I am without other
resources,

E.M.
