Morphology
duodecimal = duodeci + al
Formed from a Latin numeral combining form plus the adjectival suffix '-al'; the meaning 'relating to twelve' is deducible by analogy with words like 'decimal' but the combining form is not familiar to many learners.
Etymology
Duodecimal comes from the Latin duodecim 'twelve', formed from the parts duo 'two' and decem 'ten', and it is related to the English word dozen. So a duodecimal is one of twelve equal parts, a 'twelfth'.
