To: John Cowan Status: RO Re things like {le mo'u zdani}... My knowledge of Lojban grammar comes chiefly from the BNF version (24.2.1991), and it lists the following basic types of tense-aspect tags which can be used alone or in combination: BAI (modality); ZI (scalar magnitude of tense); PU (tense, time-offset); roi (quantified tense); TAhE (tense interval property); VA (distance in space-time); FAhA (superdirection in space-time); fe'e (space interval distributive aspect); CAhA (actuality/potentiality); fi'o ; cu'e (interrogative). It doesn't say that ZAhO can be used independently as a tag without being preceded (and eventually followed) by an . What is going on? Is the BNF grammar just incomplete in this regard, or has this usage become legal after 24.2.1991? Ivan
