This doesn't make sense, does it?

[pxenari]

These two phrases do not make sense, or at least now that i re-read them they don't. Do you understand what I am trying to say in the following?

1. Nga terkatsup sre oer.
2. Nìrangal tirvaron oe set ngahu.

And I tried to make what I think is a new word (It wasn't in the dictionary)

Po txamìng ha'ngiram ...  He left last afternoon

[wm.annis]

1. Nga terkatsup sre oer.

You shouldn't ever use a word with both an adposition and a case ending.  So, sre oe, instead of *sre oer.

2. Nìrangal tirvaron oe set ngahu.

That seems fine.

Po txamìng ha'ngiram ...  He left last afternoon

That's fine, too.  The suffixes for "previous" and "next" on that word are ok.
