In a way that can be clearly explained or described with specific limits or boundaries.
From definable (able to be defined) plus -ly (adverb marker). Definable comes from Latin definire (to set bounds), from de- (completely) and finire (to finish or limit).
The suffix -ly transforms adjectives into adverbs, but 'definably' is interesting because it describes the quality of being able to draw a line around something—it's about the possibility of creating boundaries itself, which is surprisingly philosophical for what seems like a simple adverb.
