Scholars have investigated the variable use of subject personal pronouns (SPP) in oral and written discourse using a sociolinguistic framework for over three decades. The focal point of their research has been to determine the linguistic, stylistic, and social factors that influence speakers to express or not express the SPP as in Yo canto (I sing), and Canto [(I) sing]. Several linguistic, stylistic, and social factors have been found to condition the use of the expressed SPP. Nonetheless, this syntactic variable remains highly debated among scholars who investigate Spanish in the US, Latin American, and Peninsular varieties. The remarks in the article are suggestive rather than probative as the discussion represents an overview. It also provides a gateway of interest regarding this feature. Given the many empirical studies that have investigated this feature, the metaphor of ‘the bend in the road’ represents a slight turn that should guide our thoughts for future research.
