'sealant' originates from the word 'seal,' which comes from the Old French word 'siel,' meaning 'a mark or stamp.'

'seal' evolved from the Old French word 'siel' and eventually became the modern English word 'sealant' by adding the suffix '-ant' to denote an agent or substance.

Initially, 'seal' meant 'a mark or stamp,' but over time it evolved to mean 'a substance used to block passages.'
