等爸爸刮掉纸团，立刻桌上墙上贴满了五彩的碎片，地板上也有，就像大拇指的指甲。

As my father scraped off clots of newspaper, a confetti of what looked like thumbnails stuck to the table, the walls, the floor.

我用拇指指甲拧紧了灯上的螺丝。

I used my thumbnail to tighten the screw on my lamp.

《柯林斯英汉双解大词典》

给宝宝一个安抚奶嘴，帮她找到自己的拇指；或者，悄悄地把你自己已经弄干净的小拇指放进她嘴里，指甲朝下。

Offer the baby a pacifier, help her find her thumb, or slip your own clean pinkie into her mouth, nail side down.
