Other forms: exasperatedly
It’s understandable if you get exasperated, or really frustrated, if you’re standing in the supermarket's express lane and everyone in front of you has way more than the 10-item maximum.
Over the centuries, nothing much has happened to the definition of this word — the Latin original means "irritated to anger." Speaking of which, let's get back to the supermarket, a veritable hotbed of exasperated people pushing wobbly-wheeled shopping carts their children try to fill with cartoon-branded junk food, brushing past unstable store displays that come tumbling down, enduring inoffensive but flavorless supermarket music, and emerging into the cold light of day unable to remember where they parked the car.
