An attractive or alluring quality can make something tempting. Think about your favorite dessert - maybe its delicious smell and taste are what make it tempting.
When we talk about temptation, often it's in a way that implies someone is trying to convince us to do something we might not want to do, like buying an expensive car or taking a big risk. For example, a salesperson might use our desire for a new gadget as a way to tempt us into making a purchase. Tempting can also describe things that are hard to resist because they're fun or exciting, like going on a wild adventure or trying a new hobby. In either case, the word is about something drawing us in and making it difficult to say no.
Attractive, appealing, enticing.
