Words before a contingency plan

IFNOT

Think of a phrase that introduces an alternative scenario in programming or logic, often paired with "then" in some languages.

This clue plays on the phrase "if not," which often introduces a backup or alternative plan—essentially a contingency. The answer is written as one word, "IFNOT," instead of two to fit crossword style. It’s a straightforward definition where the words literally come right before you’d mention a Plan B. Think of it like saying, "We’ll do this, if not, we’ll try that."
