The past tense of "grind" is primarily ground, though grinded is also used, especially in informal contexts.
Understanding the Past Tense of Grind
The verb "grind" is an interesting case as it has evolved to have two commonly accepted past tense forms: "ground" and "grinded." While "ground" remains the traditional and formally accepted past tense, "grinded" has gained traction, particularly in American English.
Ground: The Conventional Past Tense
Ground is the conventional and historically correct past tense and past participle of "grind." It follows the pattern of irregular verbs like "find" (found) or "bind" (bound). This form is widely considered appropriate in all contexts, especially in formal writing and academic settings.
- Usage: Preferred for formal writing, academic papers, and traditional grammar.
- Nature: Irregular verb form.
Examples:
- She ground the coffee beans fresh every morning.
- The ancient mill ground wheat for centuries.
- His teeth ground together in frustration.
- The company ground to a halt after the strike.

Grinded: An Emerging Alternative
Grinded is an alternative past tense form that has become more common, particularly in American English. It treats "grind" as a regular verb, simply adding "-ed" to form the past tense, similar to verbs like "walk" (walked) or "talk" (talked). While widely considered acceptable in informal contexts and everyday speech, it should generally be avoided in academic writing.
- Usage: Common in American English, acceptable in informal conversations and casual writing.
- Nature: Regular verb form.
Examples:
- He grinded through the tough workout at the gym.
- The skateboarder grinded the rail successfully.
- The student grinded out a last-minute essay.
- The machine grinded the plastic into tiny pellets.
You can often find both forms listed in dictionaries, such as Merriam-Webster, though "ground" is typically listed as the primary past tense.
When to Use Ground vs. Grinded
Choosing between "ground" and "grinded" often depends on the context, desired formality, and sometimes the specific meaning.
Comparison Table
| Feature | Ground | Grinded |
|---|---|---|

Practical Tips for Choosing
- When in doubt, use "ground." It is always grammatically correct and universally accepted, especially in formal settings.
- For academic or professional writing, always use "ground." This maintains a formal tone and adheres to conventional grammar rules.

- Consider the specific nuance. Sometimes, "grinded" is used to emphasize a continuous, effortful action (e.g., "he grinded through the work"), while "ground" might refer to a completed action of pulverizing (e.g., "he ground the spices").
