To make something less frequent or to visit less often.
From Middle English, combining the prefix dis- (meaning 'reverse' or 'not') with frequent (from Latin frequens, meaning 'crowded' or 'often'). The word evolved to mean reducing the frequency of something.
This word is rarely used today, but it reveals how English speakers in the 1500s-1600s systematically created opposites by adding 'dis-' to almost any word—showing how productive language creation worked before modern dictionaries standardized which words were 'official.'
