grassy
Covered with lots of green grass.
Grassy describes something covered with grass or resembling grass. A grassy field is one where grass grows thickly across the ground, perfect for running barefoot or having a picnic. A grassy hillside might be covered in green turf that waves in the breeze.
The word can also describe a smell or taste that reminds you of fresh-cut grass. Some teas have a grassy flavor, which means they taste a bit like green plants or smell like lawn clippings. Certain vegetables, like raw green beans, can taste grassy too.
When you say a place is grassy, you're usually describing somewhere pleasant and natural, not paved or covered in concrete. A grassy park, a grassy meadow, or a grassy backyard are all places where grass is the main thing growing. The word suggests softness and green growing things, the kind of place where you might lie down to watch clouds or play a game of tag.
