1. 指尖 Your fingertips are the ends of your fingers.
e.g. The fat and flour are rubbed together with the fingertips as for pastry. 像做油酥面團那樣用指尖把脂油和面粉揉搓到一起。
2. 近在手邊;隨時(shí)可用 If you say that something is at your fingertips, you approve of the fact that you can reach it easily or that it is easily available to you.
e.g. I had the information at my fingertips and hadn't used it. 資料就在我手邊,但一直都沒(méi)有用。
