Toki Pona is a minimalisot artificial language with only 123 root words created by Sonja Lang, aka. Sonja Elen Kisa.
The official site tokipona.org is now mainly publicity for the official book, aka. 'pu'.
The word 'kipisi' (to cut) didn't make it into 'pu', but it was once mentioned on the official website.
Some words were taken together in 'pu', but for most Tokiponians, they have distinct meanings.
And finally some word meanings were a bit altered in 'pu' in comparison to their usage by the TP community.
Two community words 'apeja' (shame) and 'monsuta' (monster) weren't never officialized and aren't in 'pu', but both are largely known.
Some older TP words, like 'leko' (block, stairs) , 'majuna' (old) and 'pata' (brother, sister) are also widely accepted.
I've created an expansion ('epansa') for toki pona, I deem necessary:
'luka en noka' (20 = number of digits on hands and feet)
'sa' (hour < from Swahili 'saa')
ni li epansa nanpa wan. epansa ni li wile tawa mi.
This is the first expansion. This expansion is necessary to me.
Toki Pona SIL request for a language code has been turned down anno 2007 , especially for not having larger numbers.
The same argument was used when closing down the Toki Pona wikipedia...
2017 = tu mila luka luka luka tu
1972 = mila luka tu tu kento tu wan luka en noka luka luka tu
7 000 000 000 = luka tu mila mila mila
3,14 = tu wan en nanpa wan nanpa tu tu
70% = tu wan luka en noka luka luka pi kento
