The Origin of Dairy vs Diary
Understanding their origins helps explain why English has such confusing spelling.
- Dairy: Comes from the Old English word dæġe meaning “daily” or “daily milk production.” Historically, a dairy was a place where milk was kept or processed. The term evolved to include all milk-based products.
- Diary: Comes from Latin diarium, meaning “daily allowance” or “daily record.” Originally, it referred to a daily journal for keeping track of events, money, or notes.
The similarity in pronunciation but difference in meaning is purely coincidental. English borrowed diary from Latin and dairy from Old English, creating a tricky pair for modern writers.
