unforeseen
Catching you off-guard
Unforeseen describes something not anticipated or expected: unforeseen circumstances, unforeseen consequences.
The word typically appears when explaining why plans changed or outcomes differed from expectations: Due to unforeseen delays, the project fell behind schedule.
What's unforeseen isn't merely unknown but specifically not predicted despite reasonable effort.
