yum

1. 1
   interjection

   Used to express delight at how a food or drink tastes.

   Yum, that fresh bread smells incredible and tastes even better!

   He grinned after the first spoonful of stew and murmured, "Yum."

   Similarmmm

   Oppositeyuck, ugh

   Note

   An imitative word: it turns the small sound of enjoying a mouthful into speech. It usually stands alone, either as an exclamation that comes before the compliment (Yum! This apple pie is delicious!) or as a murmured response after the first bite. The same sound also does duty as the informal adjective, so a cook can be praised with a single syllable either way.

2. 2
   adjectivecolloquial

   Having a delicious taste; very pleasing to eat or drink.

   The street vendor's dumplings were absolutely yum.

   Everyone at the table agreed the homemade jam was yum.

   Similardelicious, tasty, scrumptious, delectable

   Oppositeyuck

   Note

   Here the delighted exclamation becomes a predicate: the apple pie is yum, the dumplings were absolutely yum. It is not comparable, so it takes no -er or -est and sounds odd after more or most. To strengthen it, use an intensifier such as absolutely. It belongs to casual talk, not menus or reviews, and its natural opposite is yuck.

3. 3
   proper nounacronym

   Acronym of Yellowdog Updater, Modified: a popular package manager for Linux.

   Administrators rely on yum to manage software packages across their Linux servers.

   She used yum to resolve the dependencies before building the application.

   Note

   This yum has no connection to the food words. It is a separate coinage, and the letters stand for Yellowdog Updater, Modified, with the final M coming from the last word. Because it is a program name, it is written in lowercase and is usually the object of run: run yum, run yum in non-caching mode. Treat it as a fixed name rather than a word to inflect.
