What do we know better than our own hands, forever flashing before our eyes? What is more familiar than our fingers: thumb, index, middle, ring, little finger? Finger games, learning to count, and then – endless attempts to “explain everything on the fingers.” Yes, where without them? ..
The meaning of phraseology
Expression “like the back of my hand” means “very well, in detail, thoroughly.” The phrase is used in relation to a person who speaks with confidence about any subject and knows it in great detail.
“I know this city like the back of my hand,” a Moscow student will proudly say to his provincial friend who has come for the holidays. Just as good as your own five, you can study the character of a loved one, the weather in your native land, your pet’s habits, or the method of preparing your favorite dish.
The idiom is applicable to everything that is well known and carefully studied. After all, getting lost in five fingers is as difficult as in three pines.
Origin of expression
Phraseologism comes from ordinary everyday observations. Hands, fingers, palms are constantly in front of our eyes, and therefore, when we say that we know something like the back of our hand, we mean a familiar, well-known thing, something that is always in sight. Watching the things at hand every day, people got used to them and turned them into metaphors. And so the expression “know how the back of your hand” arose.
