Situational and rhetorical reasons for code-switching among Puerto Rican Americans

Here, code-switching means moving between English and Spanish within a conversation, sometimes within the same sentence. I might associate that term with changing how I speak in different social settings. But the opening tells us exactly what it means for this discussion. We need to use that definition instead of letting another familiar meaning take over.

The question is why people do it. The opening offers two broad kinds of explanation: situational factors and rhetorical factors. A few cases remain unexplained, but most can be explained through those factors. That is already more specific than just saying bilingual people use two languages.

Start with the situation. Who am I talking to, where are we, and what are we discussing? Those are the three factors: participants, setting, and topic. As a simple illustration, a conversation at home with a parent who shares both languages might invite a different language choice from a conversation at a licensing office with someone who doesn't. That's an illustration of why context could matter, not a rule about what every family or office does.

The technical wording can be simplified too. A domain is a social context, such as family, friendship, religion, education, or employment. Factors are congruent when they fit together naturally. The study tests how students fill in a situation and choose a language or language mix when the supplied pieces do—or don't—fit.

The researchers give the students two of the three factors. The students supply the missing one, then choose where their language use would fall on the range from all English to all Spanish. Keep those steps separate. Language choice is something the students report about the situation; it isn't one of the three factors they've been asked to assemble.

For example, give them parent and child as the participants and being a good son or daughter as the topic. They agree on home as the setting and Spanish only as the language choice. That fits the intuitive idea that a familiar family conversation can have a familiar language pattern. But don't turn this result into a claim that these families always speak Spanish at home, or that Spanish is used only for that topic.

The priest and parishioner on a beach are a less natural combination. Now the students agree less about both the topic and the language choice. We haven't been told everyone chose a particular mixture. The result is less agreement, which itself tells us something about how context affects their expectations.

Then the final paragraph complicates the situational account. Sometimes switching occurs even when the situation would lead us to expect a single language. In these cases, one language dominates while the other appears briefly for a rhetorical effect. A switch can make something sound more intimate, more humorous, or more emphatic. The situation needn't change for that expressive purpose to arise.

The family example is especially useful. Family members thought they used only English at home, but recordings caught occasional Spanish without a change in the situation. Asked about it, they said the Spanish emphasized intimacy or humor. So their self-description initially missed something their actual conversations contained. A speaker can use a familiar expressive habit without stopping to notice every switch.

My first broad summary would be that social context influences code-switching, but doesn't explain every instance. To make that summary complete, we also need the rhetorical explanation the opening announces and the family illustrates. The final example adds to our understanding of why switching happens; it doesn't erase the evidence that situation often matters.
