I relish my caramel tea in the mornings: I sip it slowly, relishing the sweet taste and the creamy texture. On peaceful spring days, I relish the sounds of birds chirping. And whenever I finish a big project, like organizing a messy closet, I step back and relish the sight of it, and I relish the feeling of being done.
Relish can also be that sense of happy enjoyment that you get when you really love doing something, tasting something, or feeling something. You can play the piano with relish, sip your hot cocoa with relish, pop a bunch of bubbles with relish, or run with your friends out to the basketball court on a bright, breezy day with relish.
Finally, because "relish" is such a wonderfully happy word, and because it often describes the joy of tasting something, people also use word "relish" to describe some spicy condiments for food, especially a kind that's tasty and green, with chopped-up pickled veggies. You might like a scoop of relish on your hot dog.
