citywide
UK: ˈsɪtiwaɪd | US: ˈsɪtiwaɪd
adj. covering or affecting an entire city
adv. throughout a city
The word "citywide" is a compound formed by combining "city" (from Old French "cité," derived from Latin "civitas," meaning "community of citizens") and "wide" (from Old English "wīd," meaning "spacious" or "far-reaching"). The fusion reflects a straightforward descriptive logic: "extending across a city." This construction follows a common English pattern of combining nouns with adjectives or adverbs to create compound modifiers (e.g., "nationwide," "worldwide").
