seriatim
Point by point; sequential.
The argument will also be the first test of the court’s announced hybrid system for oral argument, involving both the usual free-for-all questioning that was missing from the telephone arguments, and one round of seriatim questioning at the end of each arguing attorney’s presentation.
Where it comes from
From Medieval Latin seriatim, from Latin seriēs (“row, chain”) + -ātim, adverbial suffix.
