Why the double j in the word? Seen it before, not commonly seen in other languages (AFAIK), even if it is a transliteration (if that's the right term, I'm not a linguist). Does it mean extra emphasis of the j when saying the word.
Korean has some unusual consonants that are difficult to hear by non-Korean speakers but have an interesting representation in Hangul (https://en.wikipedia.org/wiki/Hangul)
The non-aspirated consonant ㅈ at the beginning of a syllable is pronounced more or less like an English 'j'. But in Korean there's a "tense" version of many of these consonants that are pronounced with more emphases. These are represented by writing the non-aspirated consonant twice. So ㅈ becomes ㅉ which transliterates to "jj".
The aspirated forms are also slightly different -- for ㅈ the aspirated form is ㅊ and pronounced more or less like the English "ch".
Korean consonants take on different pronunciations at the end of syllables and can modify in the middle or words and that's more complicated.
The nice part is that this means that you really only have to learn about 8 "core" consonants and then how they modify for each case and position. Korean vowels also have a similarly compact, easy to learn system that's different from the consonants -- there's only 5 "core" ones. It means you only have to really memorize about 11 symbols and their modified and combined forms to read and write. It takes about a week for the average non Korean speaking adult to be able to become basically literate in Korean Hangul!
Here's a list of the consonants that follow this rule (in the initial syllabic position) if you're interested:
Thanks, interesting stuff. I wouldn't have thought that a language could have so few symbols.
Sanskrit and Hindi scripts have letters like the non-aspirated and aspirated ones in your list, but I don't think they have the stressed kind, although letters (both vowels and consonants) have repeated consecutive occurrences (at least two) in words.
