Roadmap
- Proto Korean: ? to 57 BCE. A lot of mention of Altaic theory here.
- Old Korean: 57 BCE through 900s CE. It was written using Chinese Hanja. Old Korean can be constructed by tracing back Middle Korean, but is little more than a vague outline due to poor sources.
- Middle Korean: 1000s through 1500s. This can be divided into Early Middle Korean and Late Middle Korean. Hangeul was created in the 1400s and luckily gives us a great view of the phonemes involved, but the actual realisation of these phonemes is still lightly debated.
- Modern Korean: 1600s through ?. There are several ongoing changes in the 20th century and in this century, so I'm not sure what the endpoint would be. Some divide Modern Korean into Early Modern Korean and Contemporary Korean.
- Jeju language: Spoken on an island between Japan and Korea. It is conservative of Middle Korean forms.
- Yukjin language: Spoken in north-eastern North Korea. It is conservative of Middle Korean forms.

Tone
/V̀/ low tone (written without dot)
/V́/ high tone (written with "·" placed to the left of the syllable block)
/V̌ː/ rising tone with long vowel (written with ":" placed to the left of the syllable block)
The rising tone can be analysed as a long vowel which could only take the sequence, high and low tone.
