How Linguists Create Imaginary Languages

Creating languages for fictional worlds is often seen as an exercise in imagination and artistry, but emerging research suggests that the process of inventing languages—known as conlanging—may also offer measurable cognitive and psychological benefits. While traditionally associated with literature, film, and gaming, the structured mental work involved in designing grammar, syntax, and phonetics shares surprising overlap with activities known to support brain health and mental resilience.

A 2026 feature from Science News explored how linguists and language enthusiasts construct realistic fictional languages by blending, adapting, or deliberately breaking the rules of natural languages. The article highlighted that this creative endeavor requires deep engagement with linguistic principles, including morphology, semantics, and pragmatics—skills that activate multiple regions of the brain associated with memory, problem-solving, and abstract reasoning.

Although the Science News piece did not directly measure health outcomes, experts in cognitive science and neuropsychology note that tasks involving rule-based systems, pattern recognition, and symbolic manipulation—core components of conlanging—are linked to enhanced executive function and may contribute to cognitive reserve, the brain’s ability to withstand age-related decline or neurological stress.

Dr. Emily Bender, professor of linguistics at the University of Washington, explained that constructing a language forces individuals to consciously reconsider aspects of communication most people use intuitively. “When you design a language, you’re not just memorizing vocabulary—you’re making deliberate choices about how to express time, causality, social relationships, and even uncertainty,” she said in a 2024 interview with the Linguistic Society of America. “That kind of metalinguistic awareness is cognitively demanding and can strengthen mental flexibility.”

This aligns with findings from studies on bilingualism and multilingualism, which consistently show that managing multiple language systems improves attentional control, task-switching ability, and delayed onset of dementia symptoms. While conlanging does not involve fluency in a spoken language for daily communication, the mental effort to internalize and apply self-created linguistic rules may produce similar effects on neural plasticity.

Beyond cognition, some practitioners report emotional and social benefits. Online communities dedicated to conlanging, such as the Language Creation Society, describe the activity as a form of creative mindfulness—offering focus, a sense of accomplishment, and connection with others who share niche interests. Anecdotal reports from participants suggest that regular engagement with language construction can reduce stress and provide a constructive outlet for emotional expression, particularly among neurodivergent individuals who find structured systems comforting.

Dr. Suzanne Wertheim, a linguistic anthropologist and consultant on inclusive language design, noted that the act of building a language can also foster empathy. “When you create a language for a fictional culture, you have to think about what that culture values, what it avoids naming directly, how it expresses politeness or disagreement,” she said. “That process inherently involves perspective-taking, which is a cornerstone of social and emotional intelligence.”

Importantly, these potential benefits remain largely theoretical in the context of conlanging specifically. No large-scale longitudinal studies have yet examined whether inventing languages leads to measurable improvements in mental health or cognitive longevity. Experts emphasize that while the activity shows promise as a mentally stimulating hobby, it should not be viewed as a substitute for evidence-based interventions such as physical exercise, sleep hygiene, or clinically recommended cognitive training.

For those interested in exploring conlanging as a wellness-adjacent activity, resources are available through academic linguistics departments, online forums, and introductory guides from organizations like the Language Creation Society. The process can begin with simple steps—such as assigning sounds to meanings or designing basic sentence structures—and gradually increase in complexity as familiarity grows.

As interest in brain-healthy lifestyles grows, activities that blend creativity with cognitive challenge—like learning an instrument, studying a new language, or constructing one—are gaining attention for their potential role in promoting lifelong mental agility. While conlanging may never replace traditional health recommendations, its unique combination of logic, imagination, and linguistic insight offers a compelling avenue for those seeking both enrichment and mental engagement.
