Researchers at New York University led by Esti Blanco-Elorrieta published a study in JNeurosci. They tested Spanish–English bilingual speakers and used magnetoencephalography (MEG) to record brain activity with very fast timing. Participants heard a singular word such as "boat" or "barco" and were asked to say the plural form.
The team also used cognates (similar words across languages) and pseudowords like "paple". These made-up words helped the researchers see if the brain applies the same grammar rules to new words. Results showed the same brain patterns for both languages and for pseudowords, which suggests a single shared grammar system.
The study received support from the National Science Foundation and the National Institutes of Health.

Discussion questions
- Do you speak two languages? Which ones?
- Is it easy for you to make plurals in another language? Why or why not?
- Do you think new made-up words follow the same grammar rules as known words? Why?
