práha fallow ground, ploughed in autumn and left unsown till the following spring
puščati v práho to let a field lie fallow, to fallow; to allow land to lie idle
kŕcniti to fillip
kŕcniti koga po prstih to tap someone's fingers
kŕcniti madež prahá s hlač to flick a speck of dust from one's trousers
kŕcniti koga po nosu to tap someone on the nose
