The definition is at the beginning of the clue.
How the clue works
The definition is Celebration. The wordplay is an anagram of IT SAFE, with "to dance" as the anagram indicator, and the "is" in the middle just links the two parts. Shuffle I, T, S, A, F, E and you get FIESTA. The reviewer's note includes the extra IS, but that would give eight letters, so only IT SAFE is the fodder.
