Capable of being bored or drilled through; something that can have a hole made in it by boring or drilling.
From 'bore' (to drill or make a hole) plus the suffix '-able' (capable of), where 'bore' comes from Old English 'borian', related to Germanic roots meaning to perforate.
Not all materials are equally boreable—rocks, metals, and wood have different 'borability,' which is why engineers study how tools interact with materials, and why the wrong drill bit will just spin uselessly.
