opening bracket for VUhO
The binary choice of "VUhO or no VUhO" in the official grammar makes it impossible for instance to say "lo broda .e lo brode .e bo lo brodi" and attach a relative clause (or phrase) only to "lo brode .e bo lo brodi". Either only "lo brodi" receives a relative clause/phrase (simply NOI/GOI) or the entire threesome (VUhO NOI/GOI). The function of VUhOI is as an "elidable starter" - the reverse of an elidable terminator: it explicitly marks the scope of a relative clause/phrase. If elided, it extends as far as possible (equivalent to regular VUhO and consistent with elidable terminators). Examples: "lo broda .e lo brode .e bo ([VUhOI] lo brodi [VUhO] noi brodo)"; "([VUhOI] lo broda .e lo brode .e bo lo brodi vu'o noi brodo)"; "lo broda .e (vu'oi lo brode .e bo lo brodi vu'o noi brodo)". While VUhOI is elidable, it is not possible to say VUhOI and then elide VUhO; consider "vu'oi lo broda .e [VUhOI] lo brode [VUhO] noi brodo [KUhO] vu'o noi brodu" as a counterexample. See also: vu'o.
