Why do the Hebrew characters look so different?
See, for example: chart of letters
If I look at Greek, Phoenician, etc. I can still see similarities (maybe with rotations or flipping of characters) versus our current Latin system. But the Hebrew ones look very, very different. Maybe only the H is similar (and that's versus lower case h and making it grow a bit on the left). And look how massively different the "O" is. I mean, an oval or a circle or even a box or diamond all look o-like. But the Hebrew one has a couple of arrows coming out of a branch, or like two-thirds of a psi.
They just seem very, very different. Not like softened or distorted versions of common letters.
Seems like a lot of sort of flowing lines, like Arabic (but maybe Arabic comes from it?) Not the straight lines of Greek, etc.
Despite all that, some of the names are pretty suggestive of similarities (e.g. aleph). But the characters are so different?!
P.s. Apologies in advance for any imprecision of the question--I'm just a "civilian", not a language scholar. [And I did try some Googling before coming here, but wasn't finding good answer.]
