Sä

The sä proposal adds the following "forethought" conjunction patterns, replacing the official râ, rô, rî, rû:

• sä X râ Y = either X or Y (or both).
• sä X rô Y = either X or Y (but not both). (or maybe tö X rô Y)
• tü X rû Y = both X and Y.
• hï X rî Y = which of X and Y?
• sïa X bûrubu Y = neither X nor Y.
