The quality of being consequent or logically following from something; logical connection or sequence.
From Latin 'consequentia,' derived from 'consequens' (following, subsequent), from 'consequi' (to follow). The suffix '-cy' creates an abstract noun indicating a state or quality, similar to 'frequency' or 'emergency.'
This word is almost extinct in modern English, replaced by 'consequence' and 'consequentiality,' but it highlights how medieval logicians obsessed over whether effects truly *followed* from their causes.
