Short answer: opposite of each other Priceless: worth a lot. I gave her a priceless ring Worthless: worth nothing. He bought her a worthless bicycle.

"Priceless" = worth so much you can't put a price on it; "worthless" = worth nothing. Example sentences - "She gave him a priceless diamond" (she gave him a really valuable diamond); "the present she gave him was worthless" (she gave him something that wasn't worth anything). You can also use "priceless" to mean "really funny" e.g. if someone has just told a really funny joke you could say, "you're priceless", or you could apply it to a comedian you'd heard on TV.

They are the opposites of each other. Priceless means too valuable or too high in value that you cannot attach a price. Worthless means useless or no value at all. For example, a family heirloom that's passed down from generation to generation could be considered priceless. On the other hand, a car, after being involved in an accident could be considered worthless.

Priceless is an adjective that when used formally means something has such a high value that it cannot be determined. example: Archaeologists have discovered an ancient Egyptian tomb with priceless pieces of art inside. The art is valuable for sentimental and emotional value as well as money. Priceless can also be used informally or sarcastically or when a person finds something amusing. example: She told a joke that had the whole place laughing, it was priceless. It always means it was worth a lot. This can be with money or emotional/mental value. Worthless is also an adjective and it means almost the opposite of priceless. Worthless means having zero value. You could say this about a person or an object. example: The athlete contributes so little to the team that he is worthless. or I have bought this piece of forged art and it turned out to be worthless. hope this helps -Mindy

"Worthless" means that there is no price at which any buyer will pay. "Priceless" means that there is no price at which any seller would part with it.
