Something delectable is extremely delicious or appealing. Nothing tastes better at the end of a meal than an array of delectable desserts and pastries!
Don't let the de- at the beginning of delectable fool you. There is nothing negative about this word. Related to delicious through the Latin word for delight, if something is delectable, it is very tasty! Maybe your mom has promised you a delectable dinner of lobster and steak for your birthday meal?
