Case and mood inflection in Formal Spoken Arabic – a quantitative investigation research-article Andreas Hallberg Zeitschrift für arabische Linguistik, Jahrgang 2021 (2021), Ausgabe 74, Seite 61 - 86 This article presents results from a quantitative investigation of the use of case and mood inflection (CMI) in seventeen televised news-interviews (38,000 words) with Arab politicians and public figures with a variety of backgrounds. The speech of the interviewees was transcribed and annotated for realization of CMI and for relevant morphosyntactic parameters. Speakers were found to vary in the amount of CMI in their speech, but all perform far below the prescriptive ideal, with realizations of case inflection ranging from 0.2% to 42.3% (mean 7.5%, median 3.6%) and mood inflection from 0% to 68.5% (mean 9.9%, median 2.5%). Furthermore, speakers show striking similarities in how the CMI that they do use is distributed in morphosyntactic contexts. First, CMI is for all speakers used at markedly higher rates in words with enclitic pronouns and on words where CMI is orthographically represented. Second, for words with definite article, CMI is almost completely absent. Implications of these results for Arabic language instruction are discussed.
