Some words started with be- sound to me as ‘very old English’ words. Some (mainly verbs?) are quite obviously created by joining ‘to be’.
How do you make distinguish – when ‘be-’ is from ‘to be’
and when it’s a ‘pure’ (true ancient ) prefix?
Or, maybe, they (such words) all and always are from joining ‘to be’, just the second word/verb has been lost :(?
