Morphology

hexadecimal + system

This is a straightforward adjective+noun composition: if a learner knows 'hexadecimal' (meaning base‑16) and 'system', they can directly infer 'hexadecimal system' as a system that uses base sixteen. The meaning is compositional and mirrors equivalent constructions in many languages, so it is immediately transparent to learners who know the constituents.

Etymology

The term hexadecimal system comes from two parts: hex ('six') and decimal ('ten'), and together they make 'sixteen'. People use the hexadecimal system to write numbers in 'base-16' with digits 0–9 and letters A–F, which is a simple way to show computer values.
