Notes

• The definitions of e'e and e'i are based on a very lose interpretation of some of the keywords, so that they fit the e-series, which in all other cases expresses the speaker's attitude towards the audience's bringing about some situation.

• ai nai changed from rejection / refusal (which is i'a nai) to unintentionality / accidentality / unplannedness.

• e'o nai "make an offer", instead of "negative request"?

• e'u cu'i "abandon suggestion"?
