Leg
Lower Limb
noun
The kanji and the word are exactly the same. That means they share meanings as well.
Wondering how 脚 and 足 differ? You might remember 足 is mostly for feet but can sometimes refer to legs. 脚 refers to the whole leg or lower limb (often including the foot). Basically, go with 足 for feet and 脚 for legs!
The reading is the same as 足!
夜になると脚がムズムズして、よく眠れないんです。
My legs are restless at night and I can’t sleep well.
