Etymology

From Old High German sibun. The regular Central Franconian form is sivve. The form with -bb- is based on standard German sieben. According to its (limited) geographical range, it must have spread from Cologne and is probably more recent than the (also non-native) forms fönnef ‎(“five”) and sechs ‎(“six”).
