...in Standard Chinese only, other varieties having very different pronunciations, right?
- ŋjajs 議; 'discuss' - ŋjət 仡; 'powerful' - ʔjup 邑; 'city' - ʔjək 億; '100 million' - ʔjəks 意; 'thought' - ʔjek 益; 'increase' - ʔjik 抑; 'press down' - jak 弈; 'Go' - ljit 逸; 'flee' - ljək 翼; 'wing' - ljek 易; 'change' - ljeks 易; 'easy' - slek 蜴; 'lizard'
I just looked it up and the phonetic markers are only like 20-30% reliable. I am shocked at this number as in my experience I would have thought it higher (I would have guessed 60-70%), but it is definitely hit-or-miss. I've never found tones to be predictable.
