Extra means more, as well as more than more.
Tired of sidekick duty, chiming in on extra special and extra clean, extra is going solo. "She's extra," adults should note, means excessive.
Snide isn't a full-time gig. Extra still works its day job, cheering on adjectives, redoubling the efforts of nouns. It notes that gnocchi, delicious solo, are extra delicious paired with extra elements, like spicy greens, toasted mushrooms and truffle salt. The combo adds up to more than the sum of its parts. In a word, it's extraordinary.
