RT Book, Section T1 This Fragment Has Become Idiomatic, if at all A1 Fernández-Pena, Yolanda A1 Pérez-Guerra, Javier K1 Construction K1 Fragment K1 Conditional K1 Corpus K1 Diachrony AB This study examines the if-at-all construction in contemporary American English, focusing on its constructional status and historical variation. While previous research has explored reduced if-sentences (if you choose/like/prefer), constructions containing if-at-all fragments—typically occurring in factual statements—have received less attention. The study analyses 949 instances from the Corpus of Contemporary American English (COCA) spanning from 1990 to 2019. Findings indicate that if-at-all expressions meet the criteria for, from a Construction Grammar perspective, specific constructional status, inheriting features from conditional if and intensifier at all. Semantically, the if-at-all construction triggers a so-called ‘disfactualisation’ effect by casting doubt on a statement’s factuality. The diachronic analysis reveals that while the construction’s overall frequency has remained stable in recent diachrony, its usage has become more specialised, with increased preference for sentence-final placement, greater occurrence in negative polarity contexts and a decline in written registers. These trends suggest a shift toward more conventionalised spoken usage over time.
