Etymology Origin:
The word secondary evolved from the Latin secundarius, meaning "of the second rank or class." It entered Middle English via Old French secondaire, retaining its hierarchical connotation. The term reflects a clear logical progression: second (ordinal position) + ary (relational suffix), emphasizing subordination or derivation from a primary source.
