General-purpose right-bracket for arbitrary grouping of Lojban text; end highlight / selection marker.
tu'e'ei…tu'u'o is a general-purpose parentheses or grouping brackets. It explicitly supports xi subscripts to create new bracket pairs, and it explicitly does not require a UI cmavo or other indicator to follow. It does not override groupings already specified in the grammar, e.g. tanru, but since it provides a grammatical marker to select a range of text, it can be used e.g. to explicitly specify a range of text for an attitudinal to apply to. These brackets / parens simply add tokens or markers to otherwise grammatical Lojban text, and the terminator tu'u'o can be used for selecting a desired range of text to apply a UI too after the terminator, even through multiple layers of terminators. Otherwise, these general brackets can be used to select or highlight text, as general indicators that a range of grammatical Lojban text is marked for some reason. ni'o tu'e'ei…tu'u'o can cross through arbitrary terminators and tokens, e.g. «.i mi broda lonu tu'e'ei brode kei .i do broda tu'e'o brodi lonu brodo kei» is grammatical. Thus tu'e'ei…tu'u'o function grammatically more like UI than TO…TOI. ni'o Example: optional brackets (e.g. like ‘[]’ or ‘()’ in the sense of ‘optional’): « .i lo'u« mi broda lo brode [ku] »le'u cu dunli lu« mi broda lo brode tu'e'ei ma'o'ei narbilga ku tu'u'o »li'u ». ni'o Synonym: fu'o.
