means To grab hold of a person, problem, or task in order to bring it down or deal with it directly.

from Tackle traces back to a Germanic root meaning simply 'to grab' or 'equipment for grabbing/fastening' — think of the ropes and rigging ('tackle') used to haul and secure things on ships. That sense of hauling something under control carried into the idea of physically seizing an opponent in sport, and from there stretched into 'tackling' a problem, a pile of paperwork, or a plate of nachos.
