x1 (text) is written in a dialect where every bridi has arguments expressed in content/patient/recipient/stimulus semantic cases schema
Labels of roles: fa for content, fe for patient, fi for recipient, fo for stimulus, ja'i for the rules describing the semantic cases schema. Additional semantic cases might be used, e.g. sepi'o (instrument role), ri'i (experiencer role), ri'a (enabler role), gau (agent role). To be used with sei. To use only for a given bridi without affecting child bridi the transformation 'SELBRI => SELBRI .ensi' can be used (as an alternative to using sei) thus putting ensi as the tertau of a newly formed selbri. See also jo'au, ilki, esme, onga.
