Understanding the Verb Forms of “See”

To fully understand the difference between Seen or Saw, it helps to look at the complete verb family.

Verb Form	Word
Base Form	See
Present Tense	See / Sees
Past Tense	Saw
Past Participle	Seen
Present Participle	Seeing

Example of Each Form

Tense	Example
Present	I see a bird.
Present Singular	She sees a bird.
Past	I saw a bird.
Past Participle	I have seen a bird.

See	Saw	Seen

Because these forms change completely, they often cause confusion.
