Morphology

sexadecimal + notation

The noun 'notation' clearly signals a numeral/systemic notation, giving a general cue that this is a number-base term, but the form 'sexadecimal' is rare and morphologically irregular for expressing base-16 (most languages and technical usage use 'hexadecimal'). An average B1 learner who knows the parts would get a vague sense this relates to a numeric system but would not reliably infer the specific meaning 'base-16' without prior exposure or knowledge of the etymology, so it is only partly transparent.

Etymology

Sexadecimal notation comes from a word that means 'sixteen' together with notation, which means a way to write numbers. So the phrase simply names a number system that uses 'sixteen' symbols and is called 'base-16'.
