Yeri means: A Tamil word meaning lake or tank, used in Tamil Nadu, India, and Sri Lanka to refer to man-made or natural water bodies used for irrigation. Yeris were historically central to the agricultural. The word is mostly archaic or historical; you will only encounter it in old texts, period drama, or school history rather than current teen conversation. There is no real cause for parental concern; it is descriptive vocabulary rather than risky behaviour. As a place or proper-name reference it is purely descriptive.
