## In authors' words

### What they found (results)

Dependency-parsing analysis of a Spanish-Guaraní social-media corpus found Guaraní functioned as the dominant matrix language overall, with switches into Spanish concentrated at core grammatical positions (subjects, objects, obliques) and switches into Guaraní concentrated at clause-edge/discourse positions.

## Commentary

### In short

Bilingual speech is organized as a system with a dominant 'matrix' language governing overall structure, and the finding turns on a categorical distinction in where within the sentence a switch occurs -- core grammatical slots behave differently from clause-edge slots.
