disjunction
UK: dɪsˈdʒʌŋkʃən | US: dɪsˈdʒʌŋkʃən
n. a lack of connection or continuity; a sharp separation
n. (logic) a compound statement using "or" to connect propositions
n. (biology) the separation of chromosomes during meiosis
Derived from Latin disiunctio, combining dis- (apart) and iungere (to join). The morpheme junct preserves the Latin root iunct-, reflecting the idea of joining or connection. Over time, the prefix dis- inverted the meaning to emphasize separation, particularly in logic (where it denotes alternatives) and biology (chromosome separation). The suffix -ion nominalizes the action.
