Morphology
The phrase literally combines 'complex' (not simple, made of parts) and 'number', so a learner could infer it refers to a number with extra/compound parts, giving partial insight. However, the specific mathematical definition (a + bi with the imaginary unit i) is specialized and cannot be fully derived from the everyday senses of the constituents without domain knowledge, so the expression is only partially predictable.
Etymology
Complex number comes from the idea of a number 'made of two parts': a real part and an 'imaginary' part, written as a + bi. That's why it means a single number that joins a (the real part) and bi (the imaginary part).
