pro-bridi: in the second half of a bridi forethought connective expression, refers to the first half.
For example: in "ga mi broda do gi ta na gi'o'i", gi'o'i refers to "(mi) broda do". In case of nesting, the innermost connective is targeted, unless a subscript specifies otherwise: in "ge mi broda gi ga do brode gi gi'o'i", gi'o'i refers to "do brode". "gi'o'i xi re" may be used to refer to the second-innermost referent, "mi broda".
