'baggie' originates from English, specifically formed by the noun 'bag' plus the diminutive/informal suffix '-ie' (used to make a familiar or small form).

'bag' changed from Old Norse 'baggi' (meaning 'bundle' or 'sack') into Middle English 'bagge' and eventually became the modern English 'bag'; the informal diminutive 'baggie' developed later (20th century) from 'bag' + '-ie'.

Initially it meant simply 'a small bag' or 'little bag,' but over time it came to refer particularly to small plastic (often resealable) bags and acquired slang senses (e.g., packets for drugs).
