According to his Wikipedia page, Marshall Hodgson (sp) introduced "Islamicate" to describe non-religious aspects of a predominantly Islamic culture. I'm here following Bernard Lewis in using the Hellenistic/Arabic distinction to cover the situation in the Near East where communities of Jews, Christians, Muslims, etc. transitioned from publishing in Greek to Arabic, without otherwise changing their cultural identities. Greek and Arabic were the languages of publication, not daily conversation in academies. The bulk of scientific writing in the early Islamic era came from Jewish and Christian academies, so historians being careful about terminology shy away from calling it "Islamic".
