handily 可以想成用「手」在量兩件事：距離和力氣。東西如果就在手構得到的地方，你不用走過去、不用翻找、也不用花力氣。門邊的那串鑰匙在這個範圍裡；而贏得毫不費力的一場比賽，感覺上也在這個範圍裡。這個字的兩個用法，都可以想成從「伸手就到」長出來。From the word’s history
Handily is handy plus -ly, and handy is built on hand, so the adverb sits directly on the body part.
handily 是 handy 加上 -ly，而 handy 又是蓋在 hand（手）上面的。所以這個副詞從構詞上就綁著「手」，也難怪它的用法都繞著「伸手可及」打轉。

贏得不費力
把「伸手就到」從距離換成力氣：結果像放在手邊一樣，不必掙扎就到手。

Easily and by a clear amount. It is used most often about winning, beating someone, or getting through something, when the result was never close and did not take much effort.
輕鬆地；大幅領先地
