odd-numbered

The term 'odd-numbered' is a modern English compound adjective built from transparent native and borrowed elements. Its core, 'odd', descends from an Old English term for a triangle or a point, which evolved to signify something singular, unusual, or—in mathematics—an integer not divisible by two. This was combined with 'number', a word of Latin origin via French that denotes a mathematical count or quantity. The adjectival suffix '-ed' is then appended, a productive Germanic suffix meaning "possessing the qualities of", to create a descriptor for objects characterized by having an odd numerical identifier. The logic is straightforward: it literally describes something "characterized by having an odd number."

Structure: odd (not even) + number (mathematical value) + ed (having the quality of) - odd: From Old English odda (point of a triangle, third or odd number in a series), of uncertain origin, possibly from Old Norse oddi (triangle, point of land, odd number). Functions as the core adjective describing a specific numerical property. - number: From Anglo-Norman noumbre, Old French nombre, from Latin numerus (a number, quantity). Functions as the noun being modified. - ed: From Old English -ede, -ode, -ad, forming adjectives from nouns, meaning "having, provided with, characterized by". Functions as a suffix creating a compound adjective.
