Abstract
We show that an amalgamated free product admits a discrete isolated ordering, under some assumptions of and . This generalizes the author's previous construction of isolated orderings, and unlike known constructions of isolated orderings, can produce an isolated ordering with many non-trivial proper convex subgroups.
