Serfism is a word that refers to the social and economic system in which serfs were bound to land owned by a lord. The correct spelling of Serfism begins with the phoneme /s/ which is articulated by a column of air passing through a constricted space between the tongue and the alveolar ridge. The second syllable phoneme /f/ is articulated by the lower lip pressing against the upper teeth. The final syllable phoneme /ɪzəm/ is represented by the systematic, expressive use of the suffix -ism.
