H8027: שׂלשׂ‎

A primitive root perhaps originally to intensify, i.e. Treble; but apparently used only as denominative from H7969 (shalowsh), to be (causatively, make) triplicate (by restoration, in portions, strands, days or years) — do the third time, (divide into, stay) three (days, - fold, parts, years old).
