Paavli (Paavel)
Paul, perhaps a common-or-garden first or family name, perhaps after a one-time local resident but, given that the horrid agnostics across the border defrocked him (1950-1990) in favour of Popovi A., they too might have guessed the saint (feast day 25th January).
Padriku (Padrik)
Thicket, coppice.
Padu (Padu)
Low, wet place or waterlogged ground, or dense shrubbery. Parallel to Vete.
