if and when
Upon possible occurrence
If and when signals that something will happen only under certain conditions, and possibly not at all.
The phrase hedges against assuming an outcome: We'll deal with that if and when it happens.
Critics sometimes call it redundant, but the doubling serves a purpose—"if" acknowledges uncertainty while "when" implies readiness for the possibility.
