Morphology

Mississippian + period

This is a straightforward composition of a period name ('Mississippian') and the noun 'period'; if a learner knows 'Mississippian' as a geological interval and 'period' as a measured interval, the overall meaning is directly derivable. The construction follows common naming patterns for geological time units, making it immediately comprehensible to learners who know the constituents.

Etymology

Mississippian period comes from the Mississippi River area in the United States, where rocks and fossils from that long-ago time were first studied. The word Mississippian means 'from the Mississippi', so the phrase is used to name that part of Earth's history.
