如果形容某人有一个“尖的舌头 a sharp tongue”那意思就是这个人言语尖刻，说话毫不留情。
- Don't worry about what the boss says, he has a sharp tongue.
- Stephen's sharp tongue meant that nobody would ask him for advice.
值得注意的是，如果有人对你说hold your tongue那意思就是“住嘴，别说了”，说明人家不喜欢听你说得那些话。
- I'm always upsetting people at the meeting so next time I'm going to hold my tongue.
