The word "好球" is formed through a standard Chinese morphological process known as compounding, where two independent characters, each with its own meaning, are combined to create a new word with a specific semantic focus. The first character, 好 (hǎo), means "good" or "well", functioning as an adjective or adverb, while the second character, 球 (qiú), means "ball" or, by extension, a ball-related play in sports. When combined, they literally mean "good ball", but the compound functions idiomatically as an exclamation or description meaning "great shot!" or "nice play!" commonly used in contexts like basketball, tennis, or soccer to praise skillful execution. This formation exemplifies how modern Chinese creates concise, context-rich vocabulary by pairing a descriptive modifier with a core noun.
