Missing verb form - aspect: "Perfective Тerminative Cessative" ("PERF/PFV TERM CESS")

[varie]

суруй + -ан+кэбис, бар + -ан+хаал; сит + эн ыл; бырах + ан биэр

[jonorthwash]

I don't understand your examples. Could you provide the actual forms that need to analysed, and something about how they should be analysed?

[varie]

Perfective:
тардан кэбис,
кэтэн кэбис (I think кэл cannot be used in this form),
аhаан кэбис.

Тerminative:
тардан хаал,
кэлэн хаал,
аhаан хаал.

Cessative:
тардан биэр,
кэлэн биэр,
аhаан биэр.

[jonorthwash]

So currently these mostly analyse "correctly" in the Apertium sense, e.g.:

^аhаан/аһаа<v><tv><prc_perf>$ ^кэбис/кэбис<vaux><imp><p2><sg>$

хаал and биэр need to be added as <vaux>، but that's simple.

However, if it's determined that something like ^аhаан кэбис/аһаа<v><tv><perf><imp><p2><sg>$ is preferable, then this can be accomplished with either a switchable modification to the transducer (using a comment that normally gets grepped out), or a separate lsx file that's used for post-processing the analyses returned by the transducer (in a simple pipeline).

@ftyers, which option do you prefer?
