pr 3rd sg of ruccati (verb)
Etymology. From Indo-European *reuk- 'to straighten, stretch out, reach'; cognate with Sanskrit rocate 'shines, is bright', Latin rūcāre 'to wrinkle' (implying the contraction of the face in displeasure), and English rough. The semantic path moves from the physical sense of stretching or reaching toward something to the emotional sense of being attracted to or pleased by it.
