每日一词学英语(55): clubbing

Nails can provide clues to a number of underlying problems. 看指甲可以辨病(From The Times, June 22, 2009: Q&A: Why do my nails have ridges?)。

A thorough doctor will always glance at a patient’s nails during an examination. 去看病时细心的大夫会留意你的指甲，借以发现某些疾病的苗头。在各种异常指甲中，perhaps most worrying of all is the change known as clubbing where there is loss of the natural angle between the nail and the cuticle. 指甲及其根部皮肤间无自然角度就叫clubbing。

如果近期有异变，可能就和某些严重疾病有关，否则可能没事。检查方法就是把手指伸平，看看有没有这个角度(正常角度应小于165度)。
