Well I'll give this a try, just don't tell my boss what I'm really typing.
Here's my first attempt at coming up with rough Chinese single character equivalents. I've used simplified characters in keeping with the pona of toki pona. At times I have chosen less common characters. For instance I chose 言 for toki, rather than the more common characters related to speach- 说 话 语 (traditional: 說 話 語), because of its simplicity, pictographic quality (mouth + lines coming out) and because it is the radical that unites all the other characters. If measure words are available, I have used them instead of more specific nouns (see lipu, palisa) because they are often used as general classifiers in Chinese.
*Some words marked with asterisks are tp words whose sounds Sonja took from Mandarin/Cantonese. These I have kept the original phonetic characters, except for kon (which comes from 空气/空氣 (the first character-kong means free/leisure while the second-qi is the one that means gas/air etc.) and ni/li (Sonja
indicated that ni came from the character 哩 but I think she might have meant li).
Here is my favorite resource for character etymology -
http://www.chineseetymology.org - copy and paste characters here to understand the significance and history of each character and see general definitions.
Here is a great on-line dictionary -
http://www.chinesetools.eu/ - for better definitions, character stroke order, and multiple character words which give each single character context.
Any input / suggestions welcome.
