I expect I will keep adding to this list over time. Sorted by Pinyin, then by English meaning. Some character(s) may be shared between (or potentially among) homophones.
gōngkè
- 公克 gram
- 功課 homework
- 水平 level (noun)
- 水瓶 water bottle
I try to put similarly common homophones resulting from tone sandhi in this other blog entry.
