The kanji 脚 primarily represents "leg" or "foot." It signifies the lower limbs of a human or animal, used for support and locomotion. The character extends beyond just the physical limb, often implying the concept of "base," "support," or a foundational element of something.

The kanji 脚 is a phono-semantic compound (形声文字, keisei moji). It combines the phonetic component 卻 (kyaku, meaning "to retreat" or "to turn back") with the semantic component 月, which can represent "body" or "flesh" (often simplified to 月 on the left). 卻 provided the sound, and 月 hinted at the meaning related to the physical body. Thus, the kanji originally pictographically represented a leg or foot. Over time, the form of the kanji character evolved into its current shape.
