Etymology
'dual-temporal' originates from modern English, formed by compounding 'dual' and 'temporal'. 'Dual' comes from Latin 'dualis' / 'duo' meaning 'two', and 'temporal' comes from Latin 'temporalis' from 'tempus' meaning 'time'.
'dual' is descended from Latin 'duo' via Late Latin/Old French influences into Middle English; 'temporal' comes from Latin 'temporalis' (from 'tempus') and entered English via Old French and Latin scholarly use. The compound 'dual-temporal' is a modern English formation combining these elements rather than inheriting a single historical compound.
Individually, 'dual' historically meant 'two' and 'temporal' 'of time'; combined in modern usage they mean 'relating to two times' or 'involving two temporal dimensions', a meaning that follows directly from the parts and is largely compositional rather than a semantic shift.
