This paper is a study of the noun phrase construction in L2 learner language and the base for the study are the tools for measuring syntactic maturity presented by Kellog W. Hunt (1966). Hunt and other scholars have used T-units, the smallest terminable unit in language, to analyze L2 learner language. This study however, analyzes the construction of the noun phrase instead of T-units. Although the focus differs there are many similarities between the method used in this study and in those analyzing T-units. This means that the study tries to create indexes which we can use as tools for measuring syntactic maturity and complexity among L2 learners, by measuring consolidation and postmodification. The outcome of the study shows that it is possible to measure consolidation of the noun phrase and that this figure may very well function as a tool for measuring language development. Furthermore this paper investigates opportunities for teachers to teach syntax and concludes that there are ways of improving L2 teaching by utilizing knowledge about L2 learner syntax.
