Not yet decided, settled, or established; remaining uncertain or unclear.
From prefix 'un-' (not) plus 'determined' from Latin 'determinare' (to set bounds to). The concept evolved from physical boundary-setting to abstract decision-making.
The prefix 'un-' attached to 'determined' creates a useful state of suspended judgment - neither decided nor undecided, but actively awaiting determination through further evidence or consideration.
