One of my co workers said Korean was easy to write since there are a limited number of symbols, but you have to learn the stacking or whatever.
I think hangul (the Korean alphabet) is definitely one of the easiest to read and write, in terms of both learning and continuously doing it, and thus makes reading and writing the sounds of Korean relatively easy (understanding and communicating meaning is considerably more difficult). It has distinct letters representing each consonant and vowel sound used in the language. The number of letters is not that high but they can be arranged to form more complex sounds fairly easily. The rules are not too complicated and the spelling and pronunciation is remarkably consistent among the languages and writing systems of the world. There are situations in which the letters' pronunciations change based on context, but even these exceptions are rather consistent.
It's not perfect, of course, and a big caveat is that it was designed specifically for the Korean language, so rendering of foreign words, English loan words being a very common example, does not precisely match the original pronunciation.
Yes. You can write out Korean free hand relatively easily. That is a nice feature about it. ---
