'accessioner' originates from 'accession', specifically the word 'accession', where 'ac-' meant 'toward' and 'cession' meant 'a yielding'.

'accession' changed from the Latin word 'accessio' and eventually became the modern English word 'accession'.

Initially, it meant 'a coming to or reaching a place', but over time it evolved into its current meaning of 'the act of recording or cataloging items'.
