If you’re wondering about the past tense of bite, the correct answer is bit. The verb bite is irregular, so it does not become “bited” in the past tense.
Here’s the simple pattern to remember:
Bite → Bit → Bitten
- Bite = present/base form
- Bit = simple past
- Bitten = past participle
Once you understand when to use each form, this common English verb becomes much easier.
What Is the Past Tense of Bite?
The past tense of bite is “bit.”
For example:
“The dog bit my hand.”
The action happened in the past, so bit is the correct form.
You should not say:
❌ “The dog bited my hand.”
Instead, use:
✅ “The dog bit my hand.”
“Bite” is an irregular verb, which means its past form does not follow the usual -ed pattern used by regular verbs.

What Does “Bite” Mean?
Bite means to use your teeth to cut, hold, grip, or break something. It can describe people, animals, insects, and sometimes objects or situations.
For example:
- “Be careful because the dog might bite.”
- “I sometimes bite my nails.”
- “Mosquitoes bite people.”
- “The baby tried to bite the toy.”
The meaning stays related to the action, but the verb form changes depending on the tense and sentence structure.
When to Use “Bite”
Use bite as the base or present form of the verb.
You’ll commonly use bite when talking about something happening now, something that happens regularly, or something that may happen in the future.
Examples
- “Some dogs bite when they are scared.”
- “Be careful not to bite your tongue.”
- “The puppy may bite the toy.”
- “Mosquitoes bite more often during warm weather.”
You can also use bite after modal verbs such as:
- can
- could
- may
- might
- will
- should
For example:
“The dog might bite.”
Not:
❌ “The dog might bit.”
When to Use “Bit”
Use bit when talking about an action that happened in the past.
Because bit is the simple past form of bite, it can stand on its own without an auxiliary verb such as “has” or “have.”
Examples
- “The dog bit the mail carrier.”
- “I bit my lip yesterday.”
- “She bit into the apple.”
- “A mosquito bit my arm.”
- “The puppy bit my shoe.”
A useful clue is a completed past-time expression such as yesterday, last night, last week, earlier, or a few minutes ago.
For example:
“I bit my tongue yesterday.”

When to Use “Bitten”
Bitten is the past participle of bite. It is usually used with an auxiliary verb, especially has, have, or had.
Examples
- “The dog has bitten several people.”
- “I have never been bitten by a snake.”
- “She had bitten into the sandwich before she noticed the filling.”
- “He has bitten his nails for years.”
“Bitten” is also common in the passive voice:
“She was bitten by a mosquito.”
Here, was bitten is correct.
Bite vs. Bit vs. Bitten
The easiest way to understand the difference is to look at how each form works in a sentence.
| Word | Main Use | Example |
| Bite | Present/base form | “Dogs can bite.” |
| Bit | Simple past | “The dog bit me.” |
| Bitten | Past participle | “The dog has bitten me.” |
Think of the pattern this way:
Today → bite
Yesterday → bit
Has/have/had → bitten
This simple pattern can help you choose the correct form quickly.
Is “Bited” a Word?
In standard modern English, “bited” is not the correct past tense of bite.
The correct past tense is:
bite → bit
So write:
❌ “The dog bited him.”
Instead:
✅ “The dog bit him.”
The reason is that bite is an irregular verb. Its past form changes instead of simply adding -ed.
Bit or Bitten: Which One Is Correct?
Both bit and bitten are correct English words, but they serve different grammatical purposes.
Use bit for the simple past:
“The dog bit me yesterday.”
Use bitten as the past participle:
“The dog has bitten me before.”
A quick comparison:
- I bit my lip. → simple past
- I have bitten my lip before. → past participle
The word following an auxiliary verb is an important clue.
Common Mistakes With Bite

Incorrect:
❌ “The puppy bited my shoe.”
Correct:
✅ “The puppy bit my shoe.”
2. Using “bit” after “has”
Incorrect:

Correct:
✅ “The dog has bitten me.”
3. Using “bitten” as the simple past
Incorrect:
❌ “The dog bitten me yesterday.”
Correct:

4. Using “bit” after “have”
