Morphology

hexadecimal = decimal (transparent) = hexa + decimal

The prefix 'hexa-' (six) is transparently added to 'decimal' to indicate a base-16 system, which is clear to learners familiar with these components.

Etymology

Hexadecimal breaks into hexa- meaning 'six' and decimal meaning 'ten'. Think of 'six' plus 'ten' making 'sixteen', so hexadecimal is a number system that uses 'sixteen' as its base and is often used in computing for color codes and memory addresses.
