I haven't studied the particular 'issue' with that word, but thought this etym. was kind of interesting:
Akka. erū, arū (= to conceive)...
Because, in the land named for being the origin of the Sun, "eru" is the word for a large sized-something; e.g. clothing, soft drinks.
Which is to say, how "L" is pronounced. Small, medium, large end up as esu, emu, eru...
Who would ever conceive of this stuff?
Isa 7.14 Therefore the Lord himself shall give you a sign; Behold, a virgin shall conceive, and bear a son, and shall call his name Immanu-L [אל, same as the Latin letter that = 50 is spelled].
Aru is R, so L or R.
The real mystery is how he gets from point A to point B and everywhere else.
Old school.
Immanuel transmission.
by the by.... (or bye the bye..?)
hara means (currently) pregnant. Not “will/shall” conceive. It’s the classic argument.
If you look for hara, vikarat, and of course alma in any other places in a concordance you’ll get “pregnant” “and she will call” and “young woman”
