I’m Francesca, a linguist based in Los Angeles. I’m an Assistant Professor (Teaching) of Italian at the University of Southern California, USC. I’ve been a language and linguistic enthusiast since high school, and I can now share my love for it with my students.
Language switching is not a mental light switch that turns one language off and the other on. A bilingual's languages remain part of an interconnected system. Switching requires the brain to adjust which language is most available and appropriate at that moment while still letting the speaker express one coherent intention.
Mandarin has tones. German has cases. Arabic has a different writing system. Finnish is famous for its many grammatical endings, while English spelling seems to ignore its own rules. It is tempting to arrange languages on a scale from “easy” to “difficult.” Indeed, websites and language courses regularly publish lists of the world’s hardest languages. From a linguistic perspective, however, it is not that simple. No language is inherently difficult for everyone. Every typically developing child learns the language—or languages—spoken around them, whether that language uses tones, grammatical cases, complex verbs, or hundreds of characters. A language becomes difficult mainly in relation to a particular learner. The more useful question, therefore, is not “Which language is the hardest?” but “Hard for whom, and hard in what way?”
Have you ever said “LOL” aloud without actually laughing? Used “hashtag” to comment on a situation? Or described a real-life conversation as “giving XYZ energy”? If so, you have experienced the influence of social media on language. Platforms such as TikTok, Instagram, YouTube, and X do more than distribute information: they create enormous, fast-moving communities where new expressions can emerge, spread, and take on new meanings. This does not mean that social media is destroying language. From a linguistic perspective, language has always changed as people encounter new communities, technologies, and communicative needs. Social media is simply making some of those changes faster—and much more visible.
Why do familiar words sometimes disappear just when we need them most? This post explores the fascinating science behind the tip-of-the-tongue phenomenon, explaining how words are stored and retrieved in the mental lexicon. Drawing on research in linguistics, psycholinguistics, and bilingualism, it shows that these everyday lapses are not signs of failing memory but evidence of the extraordinary complexity of human language.
