Syntactic complexity in the movie retellings of 77 school-age Spanish-speaking children was examined using a structural constituent analysis. The results demonstrated developmental differences in the length of T-units, index of subordination, use of relative clauses, and prepositional phrases. There were also differences in the length of T-units, use of nominal clauses, and adverbial phrases across Spanish language groups. The analysis underscores the significance of subordination as a cohesive device and as an indicator of narrative proficiency.
