impossible
'unmöglich' and 'unrealistisch' can both say that a plan or goal is not easily achievable. The difference is in the strength. 'unmöglich' is stronger: something really cannot happen or cannot be done. 'unrealistisch' means more that something does not fit reality or is very unlikely under the given conditions. Learners may confuse the words because both can be used with plans, expectations, and deadlines. If something absolutely cannot be done, 'unmöglich' is more precise. If something could work in theory but is not reasonable or likely, 'unrealistisch' fits better.
