Morphology

even + number

The adjective 'even' directly specifies a property of 'number' (divisible by two), so the combined phrase denotes a number divisible by two; a B1 learner who knows both words can compose this meaning immediately. This is a conventional, compositional mathematical term found across many languages, making it transparently interpretable.

Etymology

Even number comes from the simple idea of pairs: imagine socks placed in matching pairs so none is left alone. An even number can be split into two equal groups with nothing left over, so it means 'a number you can divide by two'.
