When learning English, distinguishing between Seen and Saw can be tricky, but it’s all about tense, form, and how the action is framed. Saw is a simple, past tense verb used to describe a completed action at a specific time, like “I saw a movie yesterday” or “She saw a raccoon near the campsite last week.” It stands alone and does not need a helping verb, making it a standalone, single event marker.
For instance, I once saw a whale while traveling north in my SUV, and the eyes of the eyewitness could confirm it; this is exactly how Saw functions in action, observed and noticed in the past.
On the other hand, Seen is the past participle of see and always needs a helping verb such as have, has, or had to form the perfect tenses: “I have seen the Grand Canyon” or “They had seen the sunset at the park.” It’s used for actions or events that relate to experience or occurrences, often spanning time or series of observations, like a documentary on Netflix that shows wild animals or raccoons and their tracks.
Using Seen properly requires understanding subject-verb agreement: third person singular uses has seen, first person plural uses have seen, and it works in both active and passive voice, such as “The swan was seen near the pond.” My experience teaching English learners shows that mixing up Saw and Seen leads to confused communication, so practicing with examples, sentences, and observed events is essential for clarity and accuracy.
Definition of Seen and Saw
Saw is the simple past tense of the verb see. It describes an action or occurrence that happened in the past. For example:
- “Yesterday, I saw a car speeding down the highway.”
Seen is the past participle of see. It must be used with helping verbs like have, has, or had to indicate an action completed at some point before now:
- “I have seen that movie at the theater.”
Quick tip: You cannot use seen alone as a past tense verb—this is a frequent mistake among learners.
Grammar Rules: How to Use Saw vs. Seen Correctly
To use these verbs properly, remember these simple rules:
- Saw = Past Tense (Simple Past)
- Used for completed actions in the past.
- Works alone, without helping verbs.
- Example: “Jim saw a UFO while walking down the street.”
- Used for completed actions in the past.
- Seen = Past Participle
- Must appear with have, has, or had.
- Indicates an action that has relevance to the present or a past experience.
- Example: “Mariya has seen the Grandson exhibit at the museum.”
- Must appear with have, has, or had.
- Common verbs with past participles include:
- Have: I have seen
- Has: She has seen
- Had: They had seen
- Have: I have seen
Tip: When constructing sentences, the receiver of the action often matters. “I have seen the painting” is correct; “I seen the painting” is incorrect.

Common Mistakes ESL Learners Make
- Using seen without a helping verb:
- ❌ “I seen the bracelet in the shop window.”
- ✅ “I have seen the bracelet in the shop window.”
- ❌ “I seen the bracelet in the shop window.”
- Confusing past tense with past participle:
- ❌ “She has saw the movie last week.”
- ✅ “She saw the movie last week.” or “She has seen the movie.”
- ❌ “She has saw the movie last week.”
- Overgeneralizing: Some learners say:
- ❌ “Yesterday, I seen the UFO.”
- ✅ “Yesterday, I saw the UFO.”
- ❌ “Yesterday, I seen the UFO.”
Pro Tip: Read your sentence and ask: “Am I using a helping verb?” If yes → seen; if no → saw.
Usage in Spoken vs. Written English
Spoken English often includes informal errors, but native speakers usually understand:
- “I seen that movie” → Common in casual speech, but not grammatically correct.
- “I saw that movie” → Correct in both speech and writing.
Written English requires more precision, especially in documents, emails, essays, and reports:
- “Maria has seen the results of the committee meeting.” ✅
- “Billy and Mandy saw the fireworks last holiday.” ✅
Using seen or saw correctly in written communication shows professionalism and mastery of grammar, especially for ESL learners aiming to sound confident and accurate.
Participles, Conjugation, and Sentence Patterns

Sentence Patterns:

- Subject + have/has/had + seen + object → “We have seen the new artwork.”
Irregular vs. Regular Patterns:
Unlike regular verbs (walk → walked), see is irregular, so memorizing its forms is essential for ESL learners.
