the.com/slat

A plank with a purpose: too thin to be a board, too proud to be a stick.

means A thin, narrow strip of wood, metal, or plastic used as part of a frame, blind, or fence.

from From Old French 'esclat,' meaning a splinter or fragment broken off something — itself from 'esclater,' to break or shatter into pieces. So a slat is etymologically a shard that found a purpose: the splinter that got organized into something useful, like a blind or a bed frame.
