I am trying to learn the Hebrew alphabet (that is, learn the basic letters and letter forms, including final forms). I am finding this much more difficult than it was to learn the Greek or Cyrillic alphabets, both of which I learned in an hour or two each several years ago. I had no trouble with learning both Greek uppercase and lowercase as well as final sigma. I am having difficulty with recognizing the differences between the Hebrew letters due to their similarities with each other and comparative lack of similarities with Roman, Greek, and Cyrillic letters. For example, kaf and nun, and he and het appear very similar, and I have looked at an unfamiliar letter and thought "This looks like a...square? I guess that's why they call it 'Square Script', because all the letters are squares!"
How can I learn to recognize and write all of the letters of the Hebrew alphabet? At this point, I am not dealing with vocabulary, grammar, or vowelization at all - just learning the alphabet and the basics of sounding out the consonants.
I have considered starting with the Paleo-Hebrew/Phoenician alphabet, whose letters are much more obviously related to Greek and Roman ones, and then moving "forward" to the current Hebrew forms, but I am concerned that that would simply delay the inevitable and that it would not actually make learning the current Hebrew letters any easier.
I do recognize Hebrew shin and tsade as obviously related to their Cyrillic counterparts.
