betwixt and between

Neither   here   nor   there,  unresolved;  halfway between  two  alternatives.  Betwixt  comes  from  Old  English  and  originally meant “by two”; now considered archaic, it survives largely in this expres- sion, which dates from the nineteenth century. An 1877 play by Besant and Rice  (Son  of Vulcan,  1.4)  has  it, “She’s  the  fool  and  he’s  the  knave,  so  it’s betwix and between.”
