An archaic or poetic form of dishearten; to deprive of courage or confidence; to discourage.
From dis- + heart (Old English heorte). This earlier variant of 'dishearten' was common in Middle and Early Modern English, using the shorter root before -en became standardized.
This archaic form shows language evolution in real time—'disheart' gradually gave way to 'dishearten' as English preferences shifted toward longer, more explicitly verbal forms in the 16th-17th centuries.
