This study investigated the most dominant patterns of code switching in Pashto English bilingual
data. The data was collected in the form of a semi-structured interview and analyzed in the light
of the framework of the Matrix Language Frame model. The study found out that insertion is the dominant pattern
of code switching. The Embedded Language noun was the most prevalent switched element in the morpho-syntax
frame of Matrix Language. The second most embedded language insertion in the matrix language was the English
nonfinite verbs in Pashto light verb construction. The Embedded language island was the third most dominant
pattern. The switched elements in the bare DP and the bilingual VP are content words following the Morpheme
Order and System Morpheme principles of Pashto.
