The sentence is supposed to say: If the thief opened the lock box and did not break it, then he knew the process of open-operating the box-door. The sentence should use: ganai ... gi ... forethought if... then ... GEK/GIK lexeme Instead, I said: Both the thief opened the lock box and broke it, and it is false that he knew the process of open-operating the box-door. using: genai ... gi ... forethought both... and-it-is-false-that... (which may also be translated as: ... but not ... ) The story uses forethought mode here because the detective is supposed to be thinking hard about the mystery of how the thief opened the safe without damaging it. Here is what I think is the correct solution using GEK and GIK: ganai le zekri prenu goi ko'a only-if the crime person X1 ge kalri rinka le stela tanxe gi na'e porpi rinka ri both open cause the lock box and other-than broken cause it gi ko'a cu djano lo nu kalri sazru le tanxe vorme then he knows the process open operate the lock box. The if...then... construction is based on the EBNF rule: sentence-1<41> = term ... [/CU#/] bridi-tail | gek sentence-1 gik sentence-1 | The both...and... construction is based on the EBNF rules: bridi-tail<50> = bridi-tail-1 | gek-tail | tagged-tail gek-tail<51> = gek bridi-tail gik bridi-tail Incidently, I used GEK/GIK in another place, but this time with two sumti: mi faski lo za'i ge lo vorme gi lo stela na porpi I discover that the state of both the door and the lock is not broken. In this instance, the both...and... construction is based on the EBNF rule: sumti-4<96> = (LAhE | NAhE BO #) sumti-3 | sumti-5 [relative-clauses] | gek sumti gik sumti-3 where a sumti-3 may be a sumti-4. Finally, in another sentence I used afterthought GIHEK to join two bridi-tails: le minra pa ferlu lo bitmu lo loldi gi'a pa porpi The mirror fell from the wall to the floor and broke. This GIhA construction is based on the EBNF rules: sentence-1<41> = term ...
