If you get tired of learning boring standard Esperanto... ;)
- The ĉ, ĝ, ĵ, and ŝ sounds are no longer phonemic. They are allophonic.
- /j/ is now an allophone of /i/ before a vowel.
- /w/ is now an allophone of /u/ before a vowel.
- c, ĉ and ĝ are split into their constituents: ts,tŝ,dĵ
- ŝV and ĵV become siV and ziV. In rare cases where you would have a ŝ or ĵ not before a vowel, these become s and z instead. (eg. ŝtono->stono, eĉ->ets)
- ĥ is now x.
- -us (The conditional) becomes -u-, placed before the tense marker, and is now the subjunctive mood. The conditional construction is now volas Xi.
- -u (The imperative) is removed, and its replacement construction is now mi volas ti/vi Xi, or, more politely, using Xuas instead of Xi.
- All transitive verbs must use -ig-. If a verb does not contain -ig-, it is intransitive.
- All demonyms must use -ul-. If a noun does not contain -ul-, it is not a demonym.
