pigeon-toed

The term is a vivid compound adjective originating in the 18th century, drawing a direct visual analogy. The first element, "pigeon," does not refer to the bird's feet but to the inward-pointing, seemingly convergent shape of its breastbone or the way a pigeon's body is oriented, which was metaphorically transferred to describe the inward turn of human feet. The second element, "toed," is derived from the Old English word for "toe," combined with the adjectival suffix "-ed" to denote possession of a characteristic. Thus, the literal construction "having feet like a pigeon" evolved into the precise medical and colloquial term for a specific posture of the feet.

Structure: pigeon + toed pigeon: (From Old French pijon, meaning "young bird," ultimately from Latin pipio, meaning "chirping bird"). In this compound, it functions as a metaphorical descriptor. toed: (From Old English tā, meaning "toe," with the suffix -ed indicating "having the specified feature"). It functions as the core element describing the physical condition.
