This paper explores the role of language in the scientific study of politics. Conceding that politics is naturally an arena of heated disputation, it examines linguistic manifestations of factional polarisation by interpreting words, phrases, and sentences used by the Movement for Democratic Change (MDC) politicians during the party’s acrimonious splits of 2005 and 2014 and subsequent re-union of 2017. I contend that the use of vituperative, exclusionary and inflammatory language fuelled personality clashes; ethnic chauvinism; sexism; racism; ideological discord and intraparty violence. This often derailed attempts to reconcile the party’s bickering factions.
