What's the difference...?

What's the difference between "I didn't see...", "I don't see...", and "I saw..."?

"I don't see" is simple present tense. The other two examples are simple past tense. We add the auxilliary verb "to do" when we ask questions or write negative statements.

  • "I don't see" is simple present tense.

  • It these cases, the main verb (see) is always in the base form, and the auxilliary verb changes tense and number.
  • I saw her.

I didn't do it. This can be something happened in the recent past and you did not have anything to do with the event. It's past tense. i.e. I didn't go to school (yesterday). Didn't - either is expressed with an explicit past time marker, or an implied one.

I don't like to drive when IIgo to San Francisco. I take BART
