Notes

As pointed out by Kossmann (1999: 115), seeing this noun as an *m/n-derivation from bdu 'to begin', is perhaps tempting, but the verb bdu is clearly borrowed from Arabic badaʔa 'to begin'. There's no reason to think of summer as the first season, and the fact that Ghadames retains *β, whereas əbdu 'to begin' simply has b, borrowed from Arabic, suggests that these forms are indeed unrelated.
