Etymology
'archipallium' originates from Neo-Latin (New Latin), formed from the Greek prefix 'arkhi-' and the Latin word 'pallium', where 'arkhi-' meant 'chief, principal' and 'pallium' meant 'mantle' or 'cloak'.
'archipallium' was coined in Neo-Latin anatomical terminology by combining Greek and Latin elements ('arkhi-' + 'pallium') and entered scientific usage in comparative neuroanatomy to denote the principal/old pallial region; it has persisted into modern anatomical literature, though 'archicortex' or 'archaeocortex' are now more common.
Initially, the components implied a 'principal mantle' (an anatomical layer); over time the term came to denote specifically the phylogenetically older cortical region (the archicortex/hippocampal area).
