As per a primary rule, pronoun NPs functioning as subjects are typically in the nom form, whilst the obl form is used in all other syntactic functions.

Our findings suggest that both stylistic and structural characteristics, alongside considerations concerning processing, significantly influence the distribution of nom and obl. Furthermore, we note a considerable disparity in distribution when comparing spoken and written da
