Using this Wikipedia article here, I learnt that words in Standard Japanese may encounter something called sonorant gliding while converting to Kagoshima dialect. For what is written here, these are the rules that I gathered:
This occurs when there is a kana starting with the 'r' consonant not at the start of the word.
If the kana came before a kana ending in the vowels /a/ or /o/, the former kana changes the /r/ to a /y/ sound, or if no such kana exists, the whole thing becomes い.
If the kana came before a kana ending in the vowels /i/, /u/ or /e/, the former kana changes the /r/ to a /y/ sound, the former kana becomes い.
Can someone please advise me on any mistakes I have made here?
