'consider' originates from Latin, specifically the word 'considerare,' where 'con-' meant 'with' and 'siderare' meant 'to observe the stars.'

'considerare' transformed into the Old French word 'considerer,' and eventually became the modern English word 'consider' through Middle English.

Initially, it meant 'to observe the stars,' but over time it evolved into its current meaning of 'to think carefully about something.'
