🌱 Where it comes from

The word 'demarcate' entered English from the Spanish 'demarcar', meaning 'to mark out'. This itself comes from 'de-' (from) and 'marcar' (to mark). Its use was popularized by the 1494 Treaty of Tordesillas, which established a 'line of demarcation' dividing newly discovered lands between Spain and Portugal.

Demarcate is a strong, formal verb best suited for contexts where precision is important, such as in legal, political, or academic writing. In casual speech, you would more likely use 'mark out' or 'separate'. Be careful not to confuse it with 'delineate'; to demarcate is to set a border, while to delineate is to describe that border or the thing it contains in detail.
