最近有人問 Laugh 跟 Laughter 的差別, 以下是它們的差別:
'Laugh' - the sound somebody makes when they laugh. Eg "She has a loud laugh", "He has a silly laugh", "Her laugh makes me want to punch her".
'Laughter' - the act or sound of laughing. Eg "I love the sound of children's laughter", "Laughter is the best medicine", "Their laughter sounded cruel".
