The character 力 (lì): strength

A turquoise river under a golden sky, wooded hills and a red and gold pavilion among willows on the left bank. A dragon boat with a carved red and gold prow and a red drum carries five flat orange rower silhouettes leaning together, every paddle in the water on one side. On the right, above the water, the character 力 in very dark brown: a bar runs along the top, turns down the right into a hook, and a slanting stroke crosses it and runs to the lower left.

Pronunciation: lì
Strokes: 2
Radical: 力

What it means

power; force; strength; ability; strenuously

Where its shape comes from

Xu Shen sees a tendon here: "strength; a figuring of the shape of the human tendon". Palaeographers today read the earliest inscriptions quite differently, as a ploughing tool with its handle at the top and its forked point at the bottom, the very implement later written 耒 (lěi). Both readings sit side by side in the reference works. The second is the one that prevails today, and neither has been settled.

Source: Xu Shen, Shuowen Jiezi (121 CE); the Chinese University of Hong Kong character database, which follows the reading of the tool.

A way to remember it

Take 刀, the knife you have just learned, and let its slanting stroke rise. In 刀 that stroke starts from the top bar and nothing shows above it; in 力 it begins ABOVE the bar, crosses it, and a small piece sticks out on the other side. That is the whole of what separates the two characters.

This is a memory aid, not the origin of the character.
