Still working on the vowels.
One thing I learned from studying Rihanai is the usefulness of linguistic morphology in expanding vocabulary. Put simply, if you know the rules for how words are modified, you can create a whole lot of new words out of existing words. For example, take the English suffix -er. Stick it on the end of any verb and you have a new noun that means "someone who does (verb)". Wait/waiter, run/runner, sing/singer, and so on.
English mostly uses suffixes to morph words:
Agent noun suffixes
- -dar, -adar: -er; usually attached to a verb
- -dac, -ac: -er, rarer and more poetical than dar/adar
- -ta: or/ess, ist; usually attached to a noun
- -ion: no exact English equivalent, indicates a serious or devoted practitioner or artist
- -nar, -enar: servant of
Inflectional affixes
- ce-: -s, -es; partitive article indicating more than one (plural form)
- ro-: a lot; partitive article indicating a large number
- fi-: four; partitive article indicating a group of four, e.g. cardinal directions, seasons, etc.
- es-, ese-: -er (comparative)
- ri-, ris-: -est (superlative)
- : -n't (negative)
Derivational suffixes
- -en, -nen, -ren: basic adjectival suffix; adjective form of noun
- -in: variation of -en used for nouns ending in "i"; creates the ii diphthong.
- -elath, -lath: -an, -ian (adjectival suffix, of or pertaining to)
- -et, -ret: -al ( adjectival suffix, of or pertaining to)
- -ad, -iad, -es, -ail, -an: -ize/-ise (used for verbing nouns or adjectives)

- -di, -endi: -ish, (derivational suffix, of or pertaining to a people or group) e.g. Celéndi
- -në,-ney: -ish, -like (adjectival suffix, similar to)
- -kin: -ie, -y, affectionate diminutive suffix, cute or endearing
- vel-, veli-: -ing (noun, gerund) (nouning a verb to indicate the action of the verb, e.g. "the making of the film", "I like writing")

As I come up with the Esti equivalents, I'll edit this post and add them in, but just compiling the list was enough work for tonight.
