keiretsu

the word 'keiretsu' is a direct borrowing from japanese, entering english vocabulary in the latter half of the 20th century as discussions of japanese economic models intensified. in japanese, it is written as 系列, combining the characters for 'system' (系) and 'row' or 'sequence' (列), collectively conveying the idea of a lineage or grouping. the term originally referred to the hierarchical groupings of enterprises that succeeded the pre-war 'zaibatsu' conglomerates. in english, it specifically denotes the complex networks of manufacturers, suppliers, distributors, and banks linked by cross-shareholdings and long-term alliances that characterize much of japanese industry.

this is a loanword from japanese, adopted as a single lexical unit in english. it is not segmented into meaningful morphemes using english or classical language roots.
