The word that does NOT come from the Latin root -leg-, which means "law," is leggings. The words legality, legislature, and legitimate are all connected to the concept of law, stemming from the Latin root -leg-.
Legality refers to the state or quality of being in accordance with the law, the legislature is a deliberative assembly with the authority to make laws, and legitimate means conforming to the law or rules. In contrast, leggings are simply a type of clothing and have no relation to legal concepts or law.
