Precatory is an adjective that means expressing a wish.
Precari (pray CAR ee) is the Latin word that means ‘to pray.’ Over time, it has evolved into our word of the day, which is often used in a legal context to indicate something that is desired but not legally binding like a ‘precatory dress code’ in the workplace. It may also be similarly used in an everyday context: My precatory plans were for Ed to water my plants while I went out of town. But I suppose I should have made my wishes more clear before I left.
