four-legged

The compound adjective 'four-legged' is a transparent and descriptive formation from core Germanic and Old Norse elements. The numeral 'four' has ancient Indo-European roots, seen in Latin 'quattuor' and Greek 'tessares'. 'Leg' entered mainstream English from Old Norse 'leggr', replacing the Old English term 'sceanca' for this specific limb. The adjectival suffix '-ed', indicating possession, is a native English grammatical tool. The logic of the word is purely denotative, combining a count, a body part, and a possessive suffix to create a clear, classifying term for animals, furniture, or other entities possessing four limbs for support.

Structure: four (number) + leg (body part) + ed (adjective suffix) - four: From Old English 'fēower', of Proto-Germanic origin, related to Latin 'quattuor'.
