'antimension' originates from Medieval Latin, specifically the word 'antimensium', where the prefix 'anti-' meant 'instead of' and Latin 'mensa' meant 'table'.

'antimension' changed from Medieval Greek word 'antimēnion' and Medieval Latin 'antimensium' and eventually became the modern English word 'antimension'.

Initially, it meant 'instead of the table', but over time it evolved into its current meaning of 'a consecrated cloth used in place of a consecrated altar'.
