Questions & Answers about Ich arbeite sehr oft und habe keine Zeit.
Why is the verb form habe used here instead of haben or hat?
habe is the "I" form of the verb haben (to have). Because the sentence is about what "I" am doing, the verb must match Ich. The forms for "you" or "he/she/it" would be hast and hat.
Where is the subject for the second verb, habe?
The subject is still Ich, carrying over from the beginning of the sentence. Just like in English ("I work and have..."), when you connect two actions done by the exact same person with und (and), you do not need to repeat the subject. You could say ...und ich habe keine Zeit, but leaving the second ich out is very natural.
Why do we say keine Zeit instead of nicht Zeit?
In German, you use a form of kein to negate a noun (it translates to "no" or "not a"). You generally use nicht (not) to negate verbs or adjectives. Since Zeit (time) is a noun, we must use kein. It has an -e at the end (keine) because Zeit is a feminine noun.
Why does the first verb end in an "e" (arbeite)?
