This multifactorial analysis of progressive marking contrasts native English to two Asian Englishes and Dutch English. Specifically, it (i) models writers’ constructional choices (progressive vs. non-progressive) across Englishes based on several linguistic predictors simultaneously, (ii) assesses how those factors impact the progressive vs. non-progressive alternation, (iii) how several linguistic factors determine, simultaneously, writers’ constructional choices and (iv) how those choices differ across varieties and genres. Based on 4,661 verb constructions from five comparable multi-genre corpora, this study ran a logistic regression analysis to determine which factors cause English-speaking populations to differ in their constructional choices and in which specific contexts. While the model strongly predicts speakers’ choices, within individual genres, tense and modality are found to influence speakers’ choices differently. Overall, the results yield nuanced insights into the (dis)similarities among and within ESL/EFL varieties and contribute to the broader issue of the native-foreign-second language continuum across genres.
