'concluder' originates from Latin, specifically the word 'concludere,' where 'con-' meant 'together' and 'cludere' meant 'to shut.'

'concludere' transformed into the Old French word 'conclure,' and eventually became the modern English word 'conclude' through Middle English.

Initially, it meant 'to shut together,' but over time it evolved into its current meaning of 'to bring to an end.'
