Over 600 languages are spoken in New York City in addition to English—one can find Bambara spoken in the neighborhood of Kingsbridge, for example, or Ghale in Jackson Heights. English is the most common, with 65% of New Yorkers speaking it at home; Spanish is second, at 20%. A linguist hypothesizes that a Spanish dialect—a variation differing from the parent language in some of its vocabulary, pronunciation, and grammar—has developed in New York City, partly due to its linguistic interaction with English. Previous research shows that younger speakers of nonmajority languages are more likely to borrow words from the majority language of a region than are older speakers. If the linguist's hypothesis is correct, it is therefore likely to be the case that

the proportion of younger speakers who use a Spanish dialect specific to New York City is higher in neighborhoods where many languages are spoken than in neighborhoods where Spanish and English predominate.

both the number of languages spoken in New York City and the number of dialects of each of those languages will increase over time.

Spanish used by younger speakers in New York City tends to have more words borrowed from other nonmajority languages than borrowed from English.

younger speakers of Spanish in New York City would be more likely to use a dialect specific to New York City than older speakers living in the same neighborhood would be.
