Preposition doubling

[George G. Grabowicz]

This phenomenon certainly exists in Ukrainian, but it's not so much (and
mowadays hardly at all) a colloquial feature as a marked poetic one. Thus
Shevchenko begins a poem with
        U nedilen'ku u svjatuju
        U dosvitnjuju hodynu...

or (in "Irzhavec'"):
        Ne stremily b spysy v strisi
        U Petra u svata...

or Tychyna's "...v serci u mojim..."  The folkloric echo is perceptible in
each case, to be sure.
