'premeditation' originates from Latin, specifically the word 'praemeditatio,' where 'prae-' meant 'before' and 'meditari' meant 'to think or consider.'

'praemeditatio' transformed into the Old French word 'premeditacion,' and eventually became the modern English word 'premeditation' through Middle English.

Initially, it meant 'to think or consider beforehand,' but over time it evolved into its current meaning of 'planning something, especially a crime, beforehand.'
