'fissuring' originates from Latin, specifically the word 'fissura,' where 'fiss-' meant 'to split' and '-ura' indicated a result or process.

'fissura' transformed into the Old French word 'fissure,' and eventually became the modern English word 'fissure,' from which 'fissuring' is derived as a present participle and noun.

Initially, it meant 'a split or crack,' but over time it evolved to also refer to the process of forming such splits or cracks.
