This paper presents a first attempt to formally characterize the prosodic properties of Spanish acronyms. Based on the examination of a dataset and the results of a written questionnaire and perception test administered to native speakers, the stress patterns and prosodic size of Spanish acronyms are investigated. We show that stress in acronyms follows the regular stress patterns of the language. We further claim that acronyms are restricted to an upper limit of three syllables, which we explain by resorting to layered feet. Additionally, we show that an interesting minimality requirement applies exclusively to acronyms, one that must be expressed not in terms of syllable weight, but rather in terms of the number of segments.

本文首次尝试正式描述西班牙语首字母缩略词的韵律特性。根据对数据集的检查以及对母语人士进行的书面调查问卷和感知测试的结果，对西班牙语首字母缩略词的重音模式和韵律大小进行了调查。我们表明首字母缩略词的重音遵循语言的常规重音模式。我们进一步声称首字母缩略词仅限于三个音节的上限，我们通过分层脚来解释这一点。此外，我们还表明，一个有趣的最小化要求仅适用于首字母缩写词，该缩写词必须不以音节重量来表达，而是以段数来表达。
