packed

The word 'packed' originates from the Middle English verb 'pakken', which meant to press together or bundle, a term likely borrowed from Middle Dutch or Middle Low German. The core concept of compressing items into a container for transport or storage is central to its meaning. The addition of the adjectival suffix '-ed' transforms the action into a descriptive state, indicating that the bundling or filling action has been completed. Thus, the modern sense of 'completely full' logically extends from this idea of a container that has been filled to capacity, as if tightly bundled.

Structure: pack (to fill or bundle) + ed (adjective-forming suffix) - pack: From Middle English 'pak', likely from a Germanic source, meaning a bundle or to press together. Its functional role is the core lexical root. - ed: A productive English suffix of Old English origin, used to form adjectives from verbs or nouns, indicating a state or condition.
