-vi

From Proto-Finnic *-pi, probably from Proto-Uralic [Term?]. Compare Estonian -b.

-vi

1. An archaic/poetic variant of the standard third-person present.
   • 1888, John Martin Crawford, :

     Mieleni minun tekevi, aivoni ajattelevi, lähteäni laulamahan, saa'ani sanelemahan, sukuvirttä suoltamahan, lajivirttä laulamahan.

     Mastered by desire impulsive, by a mighty inward urging, I am ready now for singing, ready to begin the chanting.

-vi

1. enclitic form of vi; appended to present active infinitive verb forms to derive reflexive, accusative and dative forms when the object is second plural person

   dare (“to give”) → darvi (“to give yourselves; to give you; to give for you”)

   vendere (“to sell”) → vendervi (“to sell yourselves; to sell you; to sell to you”)

   servire (“to serve”) → servirvi (“to serve yourselves; to serve you; to serve to you”)

The final -e of the original infinitive is removed :

-are → -arvi

-ere → -ervi

-ire → -irvi

Where the verb ends in -rre, the final re is removed, leaving behind just an -r:

introdurre (“to introduce”) → introdurvi (“to introduce yourselves; to introduce you; to insert in you”)

In any case, after the suffixation, there is only a single r and no vowels immediately before -vi.
