November 2026 several of us are going to take on the 30-Day Idiom Coach4aday Challenge. Each day we will identify a ‘Saying or Expression” and explore what its origins are. For Day 9 we explore the expression “ACHILLES HEEL”

Many of the expressions we use every day have fascinating histories, cultural connections, and lessons that remain relevant today. The goal of this challenge is to explore those.
Last week, political pundits and members of the Republican Party acknowledged that the high cost of living had become their Achilles’ heel, contributing to their defeats in numerous elections. Despite other issues competing for voters’ attention, the affordability of everyday life proved to be a particularly difficult vulnerability to overcome.
