The word 'worldliness' is a layered construction in English. Its core, 'world', originates from the Old English compound 'woruld', which itself combined terms for 'man' and 'age', originally meaning "the age or life of man" and later expanding to mean human society and the physical universe. The suffix '-ly' (as '-li') was attached to form the adjective 'worldly', describing someone or something concerned with secular affairs rather than spiritual ones. Finally, the abstract noun-forming suffix '-ness' was added, creating a term for the state or quality of being worldly. Thus, the word's logic traces a path from the ancient concept of human life on earth to the modern abstract quality of being focused on material, practical, or sophisticated secular matters.

Structure: world (earthly existence) + li (adjective suffix) + ness (noun suffix) - world: From Old English 'woruld' (age of man, human existence, the physical world). Its functional role is the core semantic base. - li: A Middle English adjectival suffix (from Old English '-lic'), used to form adjectives meaning "having the qualities of". - ness: An Old English noun-forming suffix (from Proto-Germanic '-inassu'), used to form abstract nouns indicating a state or quality.
