noun

Grass is a plant with long, narrow green leaves that grows in lawns, fields, and gardens. It is also used to refer to land covered with this plant.

  • The grass is wet after the rain.
  • We sat on the grass in the park.
verb

To grass on someone means to inform the police or another authority about their secret or wrongdoing, especially in British English. It is informal and often sounds negative.

  • He refused to grass on his friends.
  • Someone grassed to the teacher.

Adinary Nuance

Grass is the everyday word for the green plant or the ground it covers. It is more general and natural than terms like "turf" or "sward," which sound more formal or literary. For illegal-crowd slang, "grass" is not the same as the plant meaning; in British English, it means to inform on someone.
