What does yum mean?
Yum is an informal English word used primarily as an exclamation of delight, particularly when tasting food. It can also function as an adjective meaning “delicious,” “appetizing,” or, more generally, “very appealing,” as in “That is a yum restaurant.” A less common noun use refers to a food or thing regarded as delicious, though the interjection and adjective are much more frequent. The word has a playful, enthusiastic tone and is especially associated with North American English, but it is now understood in informal English worldwide. Its appeal lies partly in its brevity: a single syllable can communicate pleasure, approval, or anticipation in conversation. It is better suited to casual speech, reviews, captions, and enthusiastic reactions than to formal writing. The related word yummy expresses much the same idea, often with an even more overtly affectionate or childlike tone.
An informal exclamation used to express delight or pleasure, especially at the taste of food.

Informally, delicious or appetizing; more broadly, very appealing or attractive.

Its comparative and superlative forms are yummier and yummiest.
A food or other thing regarded as delicious.
"That little chocolate cake was a real yum."
This use is much less common than the interjection and adjective uses.
The plural is grammatically possible but rarely needed because the noun sense is already uncommon.

Yum is an edible echo: a little eating sound became a worldwide food lover’s seal of approval.

Where does yum come from?
Yum entered English in the late nineteenth century as an imitative exclamation associated with the sounds of eating. It subsequently developed into an adjective meaning “delicious” and, more marginally, a noun for something delicious. The related form yummy reflects the same expressive sound with the familiar suffix -y and developed in parallel rather than as a simple inflection of yum.
