An archaic or variant spelling of corrosive; capable of eating away or destroying material through chemical action.
From Old French corosif, from Latin corrodere (to gnaw away). An older spelling that competed with 'corrosive' before standardization.
Before English spelling was standardized in the 18th century, 'corosif' and 'corrosive' both existed—this word is a fossil of an earlier era when English spelling was wonderfully chaotic!
