Stress-Epenthesis Interactions in Pakistani English: An Optimality Theoretical Analysis

Abstract

Pakistani English stands out among non-native English varieties, thanks to its own set of phonological quirks. Most of these come from the first languages of its speakers—Urdu, in particular, leaves a strong mark. One thing you see all the time? Vowel epenthesis. That’s just a fancy term for sticking in extra vowels to break up tricky consonant clusters, and it happens a lot. Then there’s the issue of stress—Pakistani English doesn’t always follow standard English patterns, putting the emphasis in places you might not expect. Here’s the thing, though: researchers usually look at these features on their own. Hardly anyone has zoomed in on how epenthesis and stress play off each other. That’s what this study does, using Optimality Theory as the framework. Epenthesis clearly changes syllable structure in Pakistani English, but no one’s really pinned down how that affects which syllables get stressed. Do these inserted vowels act like “real” vowels when it comes to stress, or do speakers avoid stressing them on purpose? And if they’re skipped over, what does that say about their place in the grammar of a second-language variety? To get at these questions, the study looks at real speech from people whose first language is Urdu. It picks out words where epenthesis happens and checks out the resulting stress patterns. The analysis leans on Optimality Theory to map out how different constraints—like avoiding complex clusters (*COMPLEX), resisting epenthesis (DEP-IO), and keeping prosodic structure in line (FOOTBINARITY, ALIGN-HEAD-RIGHT)—compete and interact. What comes out of the data is pretty clear: sometimes, Pakistani English speakers stress the epenthetic vowels to make the foot structure work; other times, they skip over them to keep the stress on the original, “real” vowels for contrast. This gives us fresh insight into how phonological grammar draws the line between what’s lexical and what’s epenthetic—a big question in Optimality Theory. By laying out the first formal OT account of how stress and epenthesis interact in Pakistani English, this study not only adds to what we know about PE phonology, but also pushes forward our understanding of constraint-based grammar in multilingual settings.
