Inflected infinitives.

Just like nouns, an infinitive can inflect according to case.

[genitive] menna > mennë

dihë profitu mennë
the benefits of going

dihë profitu ëodë
the benefits of (having) gone

[dative] fosa > fosi

One example of when this would come up involves the idiomatic use of the word saandir.

If a person wants to express the idea "I didn't buy the house", the most straightforward way to phrase this would ih hef niht dih encaas ënifda (nifa, to buy/purchase). There's a way around this.

Ih ë ënifdi dih encaas saandir.
Literally, I'm without (having) bought the house.

Höl ota ëodi saandir.
Literally, they are without (having) gone.

Ih kaa dim moca, fosi anog saandir.
I can do it without being rude.
(moca - to do, anog - rude)

Simple enough, trust me.

[Notes]

- The word "just" is pronounced and spelled just as in English.

- The suffix -pe is added to convey "friend". The plural of odtpe and idtirpe are edtupe and idtirupe (all pronounced on the very first syllable).

- mhiyë : this is a singular genitive construction, qualifying "odtpe". In the plural, the pronoun inflects just like a noun.
noa monu mhiyom - some things of mine
lo böc eosom - two books of ours

- The future expression for ih ë noa aru him ësedti saandir is ih kol noa aru him sihi saandir fosa ("It'll be a few years until I see him again" or "I won't see him again for a few years").

- ef dihë bancom : another genitive construction, this time in the plural.

- Ih ë ëmosdti arbeta afih saandir indicates that the speaker didn't have to work earlier that day. The past participle in the sentence denotes a sense of "I would have already finished work if I had to work today." If it'd been ih ë mosti arbeta afih saandir, he would be saying it early in the day, indicating that he wouldn't have to go to work later rather than that he didn't have to go earlier. Likewise, in the future construction, he'd say Ih kol mosti arbeta mora saandir fosa ("I won't have to work tomorrow"). It'd be just as easy to say mora kol ih niht mosta arbeta.
