Please go easy on me if this seems too basic and obvious, I'm a beginner.
I always had the impression that there were counters that went with the native Japanese numbers and counters that went with the Sino Japanese numbers.
But now I'm wondering if I'm wrong and that only the Sino Japanese numbers are used with all counters except for some exceptions:
- ~つ always uses native Japanese numbers:
ひとつ、ふたつ、みっつ - For counting people, only "one" and "two" use native Japanese with ~り and all other numbers use Sino Japanese with ~にん:
ひとり、ふたり、さんにん
For some reason I find it hard to search for this and what I do find seems to be poorly worded and convoluted such that I can't extract this little fact from the discussions easily at all.
