The choice to submit: freedom, gender, and the figure of God in Pentecostal Nigeria Le choix de se soumettre : liberté, genre et figure divine chez les Pentecôtistes du Nigeria

open access: yesJournal of the Royal Anthropological Institute, EarlyView.
Why do some women choose to submit to their husbands in marriage? In anthropology, the paradox of ‘chosen submission’ has famously been explored by Saba Mahmood. Her work amongst Egyptian women donning the veil in the Islamic da'wa movement spotlights the notion of ‘piety’ to explore how devotion to God can act as a powerful motivator of human ...

From Nominalisation to Passive in Old Tibetan: Reconstructing Grammatical Meaning in an Extinct Language1

open access: yesTransactions of the Philological Society, EarlyView.
Abstract Based on an analysis of the Old Literary Tibetan corpus—a corpus of the oldest documented Tibetic language—the present study provides evidence that literary Tibetan v3 verb stems (commonly termed ‘future’) initially encoded passive voice. New arguments put forward in this article range from Trans‐Himalayan nominal morphology to early Tibetan ...
