The core meaning of leg is either of the two lower limbs of the human body. Their role in propping up the body has produced the meaning of support in other objects like the leg of a chair. We also talk about giving someone a leg up when they need support and a boost. The idea of a leg as a structural support is reiterated in the phrases not have a leg to stand on and on one's last legs. A leg can equally refer to a stage of a journey or race, historically denoting sea journeys, but now with a wider application. Another common meaning of leg is that of movement in shake a leg (get moving), stretch your legs (go for a walk), and leg it (run away). The expression pull someone's leg, meaning to tease them, may originate from a Scottish rhyme where a preacher tugged on the leg of a hung criminal to make sure they were dead. Nowadays, pulling someone's leg has a more lighthearted meaning, involving teasing and joking.
