Questions & Answers about Ich kenne die Frau, und ich treffe sie morgen.
Wait, doesn't sie mean "she"? Why does it translate to "her" here?
sie can mean "she" (the subject), but it is also the accusative (direct object) pronoun for "her". In the second half of this sentence, ich is the subject doing the meeting, so sie is the object being met. Because die Frau is a feminine noun, we replace it with the feminine accusative pronoun sie.
Why does the sentence use kenne for "know"? Could I use weiß?
No, you must use a form of kennen here. German has two different verbs for "to know". wissen is used for knowing facts or information. kennen is used for being familiar with a person, place, or thing. Since you know a person (die Frau), kenne is the correct choice.
The English translation says "I am meeting her tomorrow", but treffe is present tense. Is that right?
Yes! In German, you don't need a special future tense or an "-ing" form here. It is completely standard to use the present tense to talk about the future, as long as you include a time word (like morgen, meaning "tomorrow") that makes it clear the event hasn't happened yet.
Why doesn't the verb come right after und?
