Tener, Saber, Conocer in the imperfect
As I mentioned in the section on Verbs that Say One Thing and Mean Something Else, there are words that change their meaning when put into the preterite tense from the present. These words change BACK to their original meaning when put in the imperfect.
|conocer||conozco (I know)||conocí (I met)||conocía (I knew)|
|saber||sé (I know)||supe (I found out)||sabía (I knew)|
|tener||tengo sed (I’m thirsty)||tuve sed (I got thirsty)||tenía sed (I was thirsty)|
In the next section we'll talk about sentences involving the form: How Long Ago Did It Happen?
