The word "各种各样" is formed through a deliberate, rhythmic repetition that visually and conceptually stacks the idea of multiplicity. It begins with "各" (gè), meaning "each" or "every", and pairs it with "种" (zhǒng), meaning "kind" or "type", to create the core unit "各种" ("every kind"). This unit is then duplicated into "各样" (another instance of "every kind"), and the two identical four-character phrases are joined side-by-side. This structural doubling reinforces and amplifies the original meaning, creating an emphatic, comprehensive expression that conveys "all kinds and sorts" or "a great variety".
