To cost or charge excessively; to impose a heavy cost or expense.
From dis- (prefix intensifying or indicating excess) + cost. This is an archaic or rare verb, likely formed in English during Middle English or Early Modern English period.
This is such an obscure word that it barely appears in modern dictionaries—it's the kind of word that might have been used in medieval business documents but has been replaced by simpler terms like 'overcharge'!
