Scottish pet name for Elizabeth [q.v.], from an ancient Hebrew name meaning "oath of God".

A correspondent [LP], commenting on the plethora of pet names for her own name, Elizabeth, sent the following anecdote:

• "My Gran used to tell me this old saying:
  

  'Elizabeth, Betsy, Betty & Bess, went out to seek a bird's nest. Which one got it?'

  "It took me an age to realise that we were all the same people! I also got called Beth or Bethea. I was a very confused child!"
