A tool or plow used to break up large chunks of soil or clay into smaller pieces for farming.
Compound word: 'clod' (lump of earth) + 'breaker' (something that breaks); dates to agricultural terminology when farmers needed specialized tools to prepare fields.
Before modern tractors, breaking clods was backbreaking work—this tool was so important to farming that it became one of those everyday words farmers used that most people never hear anymore.
