Watches carefully and attentively, notices or perceives something, or follows or keeps a rule, custom, or ceremony. Can mean both passive watching and active compliance.
From Latin 'observare' meaning 'to watch over, attend to' (ob- 'toward' + servare 'to keep, watch'). Entered English in the 14th century with both meanings of watching and following customs developing simultaneously.
The word 'observe' beautifully captures the dual nature of human attention - we can observe by simply watching, but we also observe rules and traditions, suggesting that true observation involves both seeing and respecting what we witness.
