The term 'unfixed' can be described in a variety of ways. One such way is with the crossword solutions of 'INDETERMINATE' (13 letters), 'FLUID' (5 letters), and 'AMBIGUOUS' (9 letters). INDETERMINATE means uncertain or indefinite, while FLUID implies something that is constantly changing or adaptable. AMBIGUOUS, on the other hand, suggests something that is open to multiple interpretations. All three words together paint a picture of something that is not fixed or certain, but rather is ever-changing and open to interpretation.
