limb
[C] Countable
pl: limbs
The term carries a clinical or biological weight when applied to anatomy, often sounding more detached and formal than simply saying arm or leg. It evokes a sense of structural utility and mechanical function within a bodily frame. When applied to botany, it suggests scale and strength. A limb is not just any twig or branch, but a primary structural extension of the trunk, implying a certain thickness and ability to support weight.
Used for individual body appendages or specific large tree branches.
