'non-eucharistic' originates from the prefix 'non-' meaning 'not' and 'eucharistic' from the Greek word 'eucharistia,' meaning 'thanksgiving.'

'eucharistia' transformed into the Latin word 'eucharistia,' and eventually became the modern English word 'eucharist,' with 'non-' added to denote absence.

Initially, 'eucharistia' meant 'thanksgiving,' but over time it evolved to refer specifically to the Christian sacrament, with 'non-eucharistic' indicating absence of this sacrament.
