Explanation
The Japanese verb '減る (へる)' means 'to decrease' or 'to diminish'. It is used to describe a reduction in quantity, size, or intensity. This verb is often used in contexts involving numbers, resources, or physical amounts. For example: the number of students decreased「学生の数が減った」(がくせいのかずがへった).
